48 Avenue is a major route that links the local and regional transportation network in Camrose. The roadway between 51 Street and 54 Street is the busiest section and with the growing population of Camrose, this section requires improvements to support the growth.

The bridge within this section has served Camrose for over 55 years and has reached the end of its life. Along with replacing the bridge, the project will add an extra lane to both the eastbound and westbound directions to accommodate the anticipated increase in traffic. The future seven lane roadway between 51 Street and 54 Street will be constructed by extending the acceleration lane on the westbound road. The additional eastbound lane will start from the 53 Street intersection and taper off before 51 Street.

48 Avenue Bridge Opening Ceremony

On November 8, from 12:30pm - 1:30pm, the City will be hosting an Opening Ceremony to celebrate the opening of the new bridge and pedestrian underpass. Everyone is invited down to the Chuck MacLean Arts Centre at 4809 - 52 Street (in the lower level of the Wild Rose co-op, on the west side). There will be an official ribbon cutting with light refreshments provided. For more information, please call 780.672.4428 or email engineer@camrose.ca. We hope to see you there!

The Bridge is Now Open!

Posted on October 23, 2018

On Monday, October 22nd, at 3:30pm, the final inspection of the bridge and walkway was completed and AMEC, PSA, and the City all agreed that the bridge was ready to be opened. Soon after that, PSA removed all barricades, and both the roadway and pedestrian walkways were opened to the public. The first cars were able to drive across the bridge at approximately 3:47pm.

With the road now open, the City and PSA have started to remove signs related to the detour routes. This will continue over the next few days. The City wishes to remind everyone that the intersections at 50 Street and 47 Avenue, as well as 53 Street and 47 Avenue have been reverted back to their original configuration, and will no longer be 4-way stops. The City plans to increase the parking bans in the area to increase the safety of those using the intersection.

Some residents may have questions about the silt fence that still exists around the bridge site. This fence was installed to ensure that loose soil does not run into the lake after a rainfall. These fences will remain in place until the sod has had time to establish its roots, and the soil is not in danger of washing away. The fence will be reviewed for removal in the spring of 2019.

The City would again, like to thank everyone for their patience and cooperation during this project. If you have any questions or concerns, please contact the Engineering Department at 780.672.4428 or at engineer@camrose.ca.

October 16 Update on the Bridge Opening

In the previous blog update, the week of October 22-26 was highlighted as the likely opening period for the bridge and pedestrian walkways. Based on the progress made since then, that prediction appears to remain on track. The only remaining tasks are the completion of the landscaping, painted line markings on the roadway, installation of the guardrails, and the handrails along some portions of the pedestrian path. With the crew planning to work through the weekend, the City expects that the bridge and pedestrian walkway could be open by as early as early next week.

Along with the good news regarding the opening timeline, the City’s consultant did complete an initial inspection of the bridge with the contractor. The City’s consultant was pleased with the work completed, and has noted only minor deficiencies on the project. Later this week, the City will be participating in another formal inspection of the bridge and the trails. Given the positive results of the previous inspection, the City does not anticipate any major issues to be identified at that time. However, before the bridge is re-opened to the public, the City will ensure that PSA addresses the necessary fixes to remaining deficiencies.

Progress Updates and What’s To Come?

Posted on October 12, 2018

With the weather mainly cooperating over the past week, PSA and Border Paving were able to make significant progress on the bridge project. As of Friday morning, all trail paving has been completed, including within the new pedestrian underpass. This marks the end of all paving related to the construction project. Additionally, topsoil has been placed in all park and boulevard areas throughout the construction site.

In the coming week, PSA plans to install the posts and guardrails, as well as begin placing sod within the landscaped areas. The City expects that the final cleanup of the roads and project area will take place during the week of October 22 – 26, weather permitting. During that week, the line markings will be painted on the road, the safety barricades will be removed, and the new roadway and pedestrian trails should be opened to the public.

In the coming weeks, the City will be sharing information about an upcoming opening ceremony for the bridge and pedestrian underpass. This will be happening a few weeks after the bridge is open to the public, to celebrate the completion of the project.

October 9 Project Schedule Update
Another on-site meeting was held on Thursday, October 4. AMEC, PSA, and the City met to review progress on the bridge project.

Since the previous update, Fortis Alberta has installed the streetlights along the length of the roadway, and the 53 Street signal lights are currently being tested to ensure they will work properly on opening day. Work continues with the preparation of the base for the pedestrian trails. As it sits now, the plan is for PSA and Border Paving to complete the east side trail paving first, before moving to the west side. Once they begin on the west, the landscaping crew will begin their work on the east, eventually transitioning to the west once the paving is complete there. While this final landscaping is being done, PSA plans to have all the road line markings completed and the guardrail installed along the road. The guardrail is not being installed until after the paving is complete, as it would get in the way of the trail paving. This issue provides some operational challenges regarding the possible early opening of the bridge. While PSA continues to look into options to open up the bridge and roadway before the rest of the project is complete, they have flagged some concerns related to the scheduling of some of their subcontractors.

In regards to the project’s remaining time, there was about a two week loss in progress from all the wet, cold weather from the previous weeks. Weather permitting; the updated project completion date will likely be toward the end of October. Along with the completion of the project, the City is tentatively planning for an official ribbon cutting ceremony to take place in early to mid-November. More information will be provided as we get closer to this time.

Update on the Roadway Progress

Posted on October 1, 2018

As you may have seen, PSA has now placed the final layers of asphalt on the roadway. With roadway paving now complete, PSA immediately moved into the pouring of concrete center median along the length of the road. All of this work was completed late last week. At the same time, Border Paving started preparing the base for the paving of the pedestrian trails. Weather permitting, this will take about 2 weeks to complete. While Border Paving works on the trails, and the concrete median is allowed to cure, PSA will make progress on the line painting and guardrail installation. Fortis Alberta will also install new streetlights along 48 Avenue before the road is re-opened.

Considering all of the work yet to be finished, the City believes that this project will be complete by mid- to late-October. The City is in initial planning stages for an official grand opening and ribbon cutting ceremony in early November, which should be approximately two weeks after the road and trails are open to the public.

The City has asked PSA about the possibility of re-opening the roadway to the public while PSA continues work on the landscaping and the trails. At this time, it is unlikely that this will be possible. If PSA was to re-open the road before the project’s completion, it would effectively turn the single construction site into 4 smaller construction sites. This would drag out the time that PSA’s workers and subcontractors to complete their remaining tasks, and would reduce safety to workers as compared to the safety inherent in a single controlled site. The City is pleased that PSA considered the possibility of this early opening, but in the interest of the workers safety and the projects efficiency, the road will likely remained closed until the project is complete.

Update on How the Weather Is Affecting the Project

Posted on September 24, 2018

On Friday, September 21, 2018, the City met with PSA and AMEC for another construction meeting. During this meeting, PSA gave more information to the City on how the recent wet weather has affected the project’s schedule. PSA and Border Paving were able to place the first 2 layers of asphalt pavement over the gravel road base. There are two additional layers of asphalt that still need to be placed. Border Paving worked hard to ensure that the first few layers were in place before any further wet weather came. By placing these first asphalt layers, this removes the threat of the gravel base under the road becoming saturated with water, which would have further delayed the project. Once the weather clears up, PSA plans to continue work on the roadway paving, as well as the construction of the new trails.

While PSA wasn’t able to complete the asphalt paving during the recent wet weather, they were able to complete work on other tasks since the last construction progress meeting. Work is nearing completion with the electrical work around the bridge site, and PSA was able to start work around the Wild Rose Co-op gas bar exit onto 48 Avenue.

As the weather clears up, and PSA is able to continue work on the remaining tasks for this project, PSA plans to provide the City with a specific date when they anticipate completing this project and re-opening the roadway. As it sits now, the recent wet weather has put the project behind schedule another 7 to 10 days or so, meaning that the project completion date will now likely be in mid- to late-October.

How has the weather affected the bridge project?

Posted on September 19, 2018

There has been a bit of a delay with the road paving at the bridge site. AMEC and PSA had planned to start the paving at the beginning of last week. This plan was delayed due to the unexpected snow and rainfall. As seen in the photos below, PSA and Border Paving are taking advantage of the milder weather while we have it. With additional wet weather in the forecast, they are trying to have as much of the road paved as possible. However, as some of the existing gravel areas on the west side of the project have yet to dry out from the last rainfalls, some of this initial paving work may be delayed to next week.

The weather delays have affected the overall schedule of the project. The details of the schedule changes will not be known in full until the next construction meeting, scheduled for Friday, September 21. After this meeting, the City will provide a further update.

September 7 48 Avenue Bridge Project Update

On Thursday, September 6, PSA, AMEC, and the City had another on-site meeting. PSA updated the City on the construction progress. Since the previous meeting, the weather proofing on the bridge deck has been complete, and all the curbs have been installed.

PSA also gave a detailed update of the remaining tasks. By the end of this week, PSA will have poured the concrete median that goes across the bridge. The rest of the median along 48 Avenue will be constructed after the road paving is complete. Over the weekend, the prep work on the roadway will be completed, and the road paving will begin next week, starting on the east side of the project. PSA anticipates that both sides of the project should be paved within the next two weeks, weather permitting. After the roadway is paved, PSA will start installing the guardrails that will separate the road users from the pedestrians on either side of 48 Avenue. PSA will also start work on installing line markings on the roadway, as well as start work on the trail paving. Currently, PSA expects that these tasks will be complete by the end of September. PSA will start work on the new landscaping after all the road and trail work is complete. PSA anticipates that the landscaping will be complete by early to mid-October, as previously predicted.

Another task completed by PSA over the past two weeks is the installation of silt curtains along the edge of the roadway. This silt curtain is installed to keep loose clay and dirt from being washed into the lake. This curtain will remain in place until after the planted sod has established a strong root system. Given the current timing of the project, the silt fence will likely remain installed until next spring, at which point PSA will remove the curtains.

During the past two weeks, workers from the City removed the pedestrian crossing signal infrastructure at the 51 Street crossing of 48 Avenue. With the upcoming opening of the bridge and underpass, the City intends for users to use either the new pedestrian underpass or the existing crossing at 50 Street if they wish to cross 48 Avenue. “No pedestrian crossing” signage will be installed at 51 Street soon, and the City thanks everyone in advance for their assistance with using the new crossing locations.

August 24 48 Avenue Bridge Project Update
On Thursday, August 23, AMEC, PSA and the City met for another on-site construction update meeting. In the meeting, PSA mentioned that they are mindful of the current poor air quality resulting from the BC fires, but that it has not significantly affected their staff or overall progress on the project.

Over the last two weeks, PSA has completed all of the necessary changes to realign the roadway onto its final alignment. PSA has also completed installation of wiring and fixtures for the pedestrian underpass lighting. On the east and west sides of the project, the roadway subbase is complete and the initial layer of gravel has been placed and is compacted.

In the coming days, PSA’s concrete sub-contractor will start installing curb and gutter on the east side of the project site. As this continues on both sides of the project and as the center median is constructed, Border Paving will be able to place the remaining gravel base and start paving the new roadway. In the meantime, Fortis plans to start installing underground wiring and the bases for the new street light poles sometime next week, with the final street lights being installed after paving is complete. PSA anticipates that they will complete all paving by mid- to late-September, followed by the installation of line markings and guardrails. PSA plans to start work on landscaping for the project by mid-September, although this will continue through the end of the project by mid-October.

August 13 48 Avenue Bridge Project Update
Since the last update, the design changes and new timeline have been approved. As stated in a previous post, the south walking trail going across the bridge will be reduced from 4 metres to 2 metres in order to accommodate a wider roadway. Even with the changes, the project remains on budget, and a new finish date has been set for early to mid-October.

Another on-site meeting was held on August 9, 2018. Everyone was happy to hear that there were no safety issues at the bridge site as a result of the Big Valley Jamboree traffic. The City did inform PSA that there was a recent accident along one of the bypass routes (at 47 Avenue and 50 Street), and that the City has made some changes along the bypass to minimize the risk of this happening again.

During the meeting, PSA detailed the work that they completed in the past two weeks, and what they expect to complete in the next few weeks. On the east side of the bridge, Border Paving has started preparing the sub-base for the roadway. In about two weeks, they will be finished on the east side and will do the same for the west. Once the sub-base is ready, Border will start placing and compacting gravel for the new base of the roadway. On top of this base, Border and PSA will construct the future roadway, including the concrete curbs, gutters and medians, as well as the asphalt paving. Currently on the west side, the bases for the traffic lights just north of the intersection at 48 Avenue and 53 Street are being adjusted into their final position.

As mentioned above, with the design edits approved, PSA is working hard to realign the roadway on the bridge. A crane was on site on August 9th to remove two of the existing girders. Once the girders were removed and the site prepared, the crane was able to successfully reposition the girders in their final locations. With that work not done, PSA can re-pour the sections of the approaching concrete slabs that had to be removed.

July 30 48 Avenue Bridge Project Update
July 26 was a busy day on the 48 Avenue construction site. Both a council/media tour took place, as well as another on-site meeting between AMEC, PSA and the City.

The tour consisted of members from the City Council, as well as a few representatives from the local news media. After a safety orientation, PSA and the City led the group through the project to see the various things being done on site. Keep an eye out in your local media for pictures and information from that tour.

Following the Council and media tour, the City participated in the scheduled construction meeting. During this meeting, PSA updated the City and AMEC on some of the work that has been recently completed, as well as PSA’s plans for the next two weeks. PSA has recently installed handrails on the retaining wall and the bridge structure. Many of the rails are in their final positions, and are waiting to be grouted. Along with the handrails, PSA continues to work on the earthwork in preparation for roadway construction. The side slope near the south entrance to the pedestrian walkway is nearly finished, and the roadway is just about ready to be handed off the Border Paving.

During the construction meeting, the City and PSA discussed the increase of traffic that is expected to happen with the upcoming Big Valley Jamboree music festival. The City expects this to have minimal direct impacts on the bridge site, as the majority of the traffic coming from the west tends to use Camrose Drive. Even knowing this, the City plans to put up more signage that is specific to the BVJ traffic, both as they funnel in throughout the week ,and as they all leave at the end of the festival. PSA said they did not expect to be working during that weekend, but will keep this information in mind in the event that their plans change.

July 13 48 Avenue Bridge Project Update

Posted on July 13, 2018

Another on-site meeting was held on July 12th between AMEC, PSA, and the City.

PSA informed the City that the east side of the project is nearly ready for Border Paving to take over. Once Border Paving starts working on site, they will begin building the roadway base, the curbs, sidewalks and the actual roadway. The retaining wall adjacent to the Wild Rose Co-op staff parking lot is almost finished, all asphalt has been removed, and the roadway has been built up to its new elevation.

On the bridge itself, the approaching concrete slabs were poured on the evening of July 9th, and the grouting between the girders will be completed within a few days.

On the west side of the bridge, progress continues to be made with removing the old asphalt. Once Border Paving has begun their work on the east side, PSA can focus more on completing the west side as well. PSA also explained their plans to remove the sediment curtains seen in Mirror Lake within a week or two, as work on the banks of the lake come to a close.

During the meeting, there was also a discussion on the possibility of expanding PSA’s scope of work to include some additional sidewalk and road upgrades. If this were to happen, there may be a slight delay to when the project is complete (about one additional week), but should not substantially affect the overall budget.

Overall, the City is pleased with how the various detour routes are functioning. We are aware of some operational challenges that do exist on a few of the detour routes, and the City is seriously reviewing the current traffic accommodation plan to see what changes could be made to further improve the safety and traffic operations. As part of that review, the City is investigating ways to better route large trucks and non-local traffic around Camrose using the outer bypass route (Camrose Drive and 68 Street).

The original design. The exterior lanes in both the eastbound and westbound roadways transition from roadway, immediately to the curb.

 

New plan for the bridge design. The girder that contains the south roadway railing will be rotated 180 degrees (east for west), and switched with the flat girder directly south of it. This will narrow the south walkway, in order to create the needed width to maintain desired safety standards for the roadway.

June 29 48 Avenue Bridge Construction Update

Posted on June 29, 2018

On Thursday June 28th, there was another on-site meeting between the City, AMEC, and PSA. The meeting had many updates, as much has happened on the bridge site since the last project meeting.

The past week has seen some windy days, and as a result, PSA has had to repair and replace some damaged road signs. Despite this, traffic remains a non-issue to the workers and the project.

Since the previous meeting, the storm sewer systems related to the new bridge and roadway has been installed, and the fill material between the pedestrian underpass and the east back wall has been placed. Along with this, much of the team continues to work on the newly installed bridge girders, securing them in place, and prepping them for roadway construction. Starting at the end of next week, PSA will start pouring concrete for the bridge approaches. On the east side, the retaining wall adjacent from the Wild Rose Co-op staff parking lot is nearly complete, and the handrails will be installed soon after its competition. Likewise, in the coming weeks, the handrails for the top of the north and south ends of the pedestrian walkway will be installed.

Once PSA has completed their earth work on the east side, the track hoes and workers will continue the same work on the west side. Border Paving will soon come on site to begin preparations for the roadway construction between the new bridge and 51 Street.

The City would like to inform everyone that starting in the next few days, the south exit from the Co-op gas bar onto 48 Avenue will be closed off. PSA predicts that the closure will be for the next 6-7 weeks. The City recognizes the inconvenience of this closure, and would like the thank Co-op patrons for their patience and understanding.

Similarly, the City would like to inform citizens that the existing crosswalk at 51 Street (across 48 Avenue) will be permanently removed within the next few weeks. As part of the scope of this project, this cross walk will no longer be available as citizens will ultimately be able to cross 48 Avenue using the new pedestrian underpass and the cross walk at 50 St.

To maintain progress, PSA noted that they plan to work on the Saturday of the upcoming long weekend. PSA is still predicting completion of this project in early September, and is working hard to keep the project on track.

Girder Installation

Posted on June 25, 2018

Tuesday, June 19th, saw the first delivery and installation of the prefabricated bridge girders. In total, 30 girders were installed, spanning the entire width of the bridge structure which will serve as the base of the bridge’s roadway. This operation went very smoothly and was completed by the end of following day.

While the excitement has been focused on the girder installation, other important work resumed on the site such as the retaining wall construction adjacent to the Wild Rose Co-op staff parking lot (expected to be completed in the coming few days) and the build-up of the roadway base to the desired elevation.

This drawing is from the design plan of the bridge. It is a cross section, looking east along 48th avenue. In the image, one of the girders is highlighted in red. This image is to illustrate how the girders will form the base of the roadway once all are installed.

 

June 19 (around 8:00 a.m.) – This picture taken from the edge of the north trail, looking south-west. A truck has arrived on site with the first girder, and the crane prepares to move it.

June 15 48 Avenue Bridge Update

Posted on June 15, 2018

Since the last update, lots of activity has happened at the bridge project. Currently, PSA is working hard to install the new concrete foundations that will be used to relocate the existing signal lights at 53rd Street. As the concrete is being poured, Shelby Engineering is on site along with AMEC to test the concrete, assuring it meets the standards of safety expected by the City. The relocated signal lights will be slightly north of their previous locations, and will allow the construction of the new westbound lane on the north side of 48th Avenue.

On the east side of the bridge, the back wall has been completed, and the road space behind it is being built up to its new elevation. Similarly, progress has been made on the retaining wall adjacent to the Wild Rose Co-op. In a few weeks, once the retaining wall is complete, that team will move to the west side of the bridge to finish the second backwall.

Many may have noticed the large amount of earth being moved around on site. Much of PSA’s team is working hard to clear areas on site, making room for the delivery of the bridge girders. The girders are expected to be delivered in the middle of next week (around June 19th) from the off-site location where they were fabricated near Blackfalds. Once installed, the girders will span the length of the entire bridge, and will serve as the foundation for the roadway across the lake to be built on top of. In total, there will be 30 individual girders delivered.

June 4 48th Avenue Bridge Replacement Update

Posted on June 4, 2018

On May 31st another on site meeting was held between the City, AMEC Foster Wheeler, and PSA. At this meeting, PSA gave an update of their progress.

The City and PSA are both happy with how things are proceeding in regards to safety and environmental considerations. With the rainfall in the past week, steps have been taken to manage the flow of water away from the site to keep the area as safe and efficient as possible for workers. Similarly, they are continuing to monitor water runoff to ensure the water quality within Mirror Lake and Camrose Creek is not affected.
Both PSA and AMEC were reminded of the upcoming Jaywalkers Jamboree event and the expected increase to vehicle and pedestrian within the City as a result. PSA confirmed that there should be no conflicts between the project and Jaywalkers.

In the previous two weeks, many events have been happening on site. The installation of the box culverts has been completed, and the pile cap has been installed on the west side of the new bridge. Along with this installation, work is now being done to construct the back wall for the west side, and will take about two weeks to complete. Once the back walls are finished, the bridge girders that were constructed earlier in the year at a factory near Red Deer can be installed on the abutments and pile caps. This is scheduled to begin in early, July. While the current work is being done, the beginning stages of utilities installation on the east side, and preparations for the new retaining-wall adjacent from the Wild Rose Co-op staff parking lot are both being focused on as well. The construction of the retaining wall will begin in about two weeks and should take about a month to complete.

Along with this long list of tasks being completed, PSA plans to start work on relocating the traffic signals at the intersection of 48 Avenue and 53 Street within the next week. The existing signal poles will eventually be placed on new bases that are north of the existing locations. This work is needed in order to construct the new westbound lane on the north side of 48 Avenue. While this signal work is happening, the City and PSA do not anticipate any further traffic restrictions at this intersection. However, the signals will need to be turned off while they are being relocated. Even once these lights are relocated, they will likely remain dark until near the end of the project.

May 25 48th Avenue Pedestrian Underpass Update

Posted May 25, 2018

As you may have noticed, there has been a lot of activity this week. PSA began the excavation across 48 Ave on Tuesday May 22. This was to prepare for the installation of the pedestrian walkway underneath the new road. Wednesday morning (May 23rd) began with the delivery of the first box culvert pieces.

The box culvert installation took place for the rest of the day, and by the end of the day on May 23rd, PSA had installed 13 of the box culverts. As of this morning (May 25th), 17 pieces in total have been installed and an additional 5 pieces have been delivered to the site. In the end, the pedestrian walkway will be made up of 32 of these box culverts. To install all of the pieces, PSA predicts that it would take about three days in total. These three days may not be consecutive, as work will first be done with the back filling and weatherproofing of the current sections. Once this first portion is complete, a ramp will be installed over the box culverts so work can be continued on the east side of the bridge.

By the end of the project, PSA will install handrails along either end of the pedestrian underpass to ensure that trail users along 48 Ave do not accidentally fall down onto the lower trails.

Inside the box culverts, they are about 4 meters wide and 2.5 meters in height. This is over 8 feet of vertical clearance, which is the height of a typical house ceiling. The high clearance is to accommodate bike riders, as to not need to crouch down inside the tunnel. The 4 meter wide path is about one meter wider than the average trail in Camrose. This extra width is to allow for pedestrians to comfortably pass each other.

The slanted ends of the underpass are designed to let in as much natural light as possible into the walkway. Additionally, there will be a total of 16 LED lights installed, with 8 on either edge along its length.

May 18 48th Avenue Bridge Update

Posted May 18, 2018

Another on-site meeting was held between representatives from the PSA, the City, and AMEC Foster Wheeler on May 17, 2018. PSA provided another update on the progress of the bridge construction.

PSA reiterated that they were happy with the system in place for traffic accommodation, and had no safety issues or concerns to report. After hearing this, and inspecting the site, the City is happy with how things are moving forward in a safe manner.

Similarly, the City is quite pleased with the manner in which environmental health and protection is being handled. In order to construct the back wall of the bridge, trenches had to be dug along the edge of the lake. To keep the work area dry, water from the lake had to be constantly pumped out of the trench. The water that is removed from the trenches is full on soil particles and debris, and would cause harm to the environment if allowed to be dumped directly back into the lake. Along with the yellow sediment curtains in place, PSA has also set up small on site ponds that will allow for the water to be filtered as it naturally feeds back into the environment.

On the east side of the soon-to-be bridge, the construction of the backwall is about 65% complete. Within the next two weeks, one of the three track hoes will be moved to the west side to continue making progress with that portion. Throughout this, PSA continues to remove asphalt and debris to make room for the new roadway.

PSA has a lot planned for the next two weeks. Starting next week, the box culverts for the pedestrian walkway will be delivered and begin to be installed. The plan is the start on the north side of the roadway and work to the south. As mentioned before, work with the track hoes will be continued on the west side. As well, initial planning has begun for the relocation of the signal lights.

Overall, the City is quite pleased with the progress being made. Current predictions of the project’s completion place it in early September. PSA is working hard to get the project back on schedule.

 

May 8 48th Avenue Bridge Replacement Update

Posted on May 8, 2018

On May 3, 2018 representatives from the City, PSA Construction, and AMEC Foster Wheeler met for an on-site meeting for the 48th Avenue Bridge Project. At this meeting, PSA updated the City on the work that has been completed on the bridge.

To date, all the pilings to support the new bridge structure have been installed on both the East and West side of the new bridge. PSA has also completed the installation of the pile cap on the east side of the new bridge. This pile cap sits on top of the abutment pilings, and will ultimately support the east side of the concrete bridge girders.

PSA also informed the City that the fabrication for the concrete bridge girders and the box culverts is now complete. The box culverts will be delivered to the site by mid- to late May, and the bridge girders will be delivered to the site in June. Subsequent to their delivery, the box culvert and girder installations will begin. Over the next few weeks, PSA will continue to work on the bridge abutments.

Over the past couple of weeks, the PSA crews have been hard at work removing loose organic material from the lake to allow for large rocks (called rip rap) to be installed to prevent erosion. However, due to the heavy spring runoff, progress on this stage of the project is going slower than expected. At this time, PSA anticipates that the project completion date may move into early September, rather than being finished at the end of August as originally planned. PSA is planning to make up for some of this lost time, including mobilizing additional equipment into the area to allow the work to progress faster.

This site meeting also included a discussion on the current traffic accommodation plan. Currently, the detour routes appear to be working quite well, and the City does not anticipate any major changes to the plan at this time.

Bridge Piling Installation nearing Completion, Fabrication of Girders and Box Culverts Ongoing

Posted on April 20, 2018

Over the past two weeks, quite a bit of work has been completed on the 48 Avenue Bridge Replacement project, both here in Camrose as well as off-site. Starting on April 9th, PSA’s pile driving sub-contractor has now completed installation of the steel pilings on the east side of the new bridge, and is well underway to completing installation of the pilings on the west side. The locations for each of the 62 steel pilings that were used for this project were precisely surveyed before the start of installation, and were measured multiple times during the installation to ensure that they were driven vertically into the ground. The pilings used for the east and west bridge abutments were driven approximately 21 metres into the ground so that they could be embedded about 1 metre into the underlying bedrock. Because of the significant length of the pilings, the pilings were installed in two sections with the top section being welded onto the bottom section before the pile driving operation resumed. The top of each steel piling was galvanized to prevent long-term corrosion of the steel.

Once all of the pilings are installed, PSA will begin installation of the abutment cap, which will sit on top of the abutment pilings and upon which the concrete bridge girders will rest. Over the next two weeks, PSA will begin work on fabricating / installing the back walls and wing walls, which will be installed on the outsides of the bridge pilings (i.e. on the side away from the water) to prevent the future road structure from spilling into the lake at the bridge opening. PSA will also begin cleaning out the lake bed within the bridge opening (i.e. between the east and west bridge pilings) to remove loose organic material, and installing additional large rocks (rip rap) between the pilings to prevent water flowing under the bridge from damaging the bridge or the roadway. Work on this component of the project will begin shortly, and will likely continue until early June.

PSA and AMEC have also advised the City that fabrication of the concrete box culvert pieces is going well, and should be complete by the end of April. Based on the current construction schedule, these pieces will be delivered to Camrose in mid-May, at which time PSA will begin installation of the pedestrian underpass. This installation will take about a month to complete, and should be done by mid-June.

Finally, PSA and AMEC have advised that fabrication of the concrete bridge girders is still on schedule for a tentative completion in early to mid-May. As these are to be installed in June and early July, fabrication on these pieces will be complete in time for the installation to begin.

April 11th – Placement of the top sections onto the bottom sections of the pilings on the east side of the bridge. These sections were welded together prior to resuming piling operations. Note the top portion of the pilings are galvanized (grey in colour) to prevent the steel from corroding over time.

 

April 18th – Installation of the pilings is complete on the east side of the new bridge. The contractor has already installed the bottom piling sections on the west side of the new bridge, and is starting to lift the top sections into place for welding.

 

April 10th – A few of the completed concrete box culvert pieces in a storage yard near Red Deer. The full rectangular pieces will be installed under the new roadway, while the angled piece seen at the right of the photo will be installed near the entrances to the underpass. Note that the weight of one of the completed box culvert pieces is over 26,000 kilograms (refer to the stamp near the bottom corner of the piece).

 

April 9th – Three of the completed concrete bridge girders in a storage yard near Blackfalds. The steel loops located on the tops of the girders are to allow these heavy girders to be lifted, and will be cut off by PSA once the girders have been placed on the abutment caps.

 

April 11th – Fabrication of one of the concrete bridge girders in an indoor facility near Blackfalds. This photo was taken shortly before concrete was poured into the mold. Note the steel rebar throughout the girder that will help provide strength to the new bridge girders. The cylindrical tubes running along the length of the girder help reduce the total weight of the girder. These have been designed to reduce the overall cost of the girder, without sacrificing the strength of the girder or its future performance.

Phase 2 of 48 Avenue Bridge Project Going Well so Far

Posted on April 6, 2018

City Administration is quite pleased with how things are going so far on Phase 2 of the 48 Avenue Bridge Replacement Project. After setting up informational and detour route signage around the City, the full closures for 48 Avenue came into effect on Monday, March 26th. Since that time, PSA has completed the removal of the pedestrian walkway bridges and most of the roadway bridge.

On Friday, April 6th, the pile driving sub-contractor mobilized their equipment and materials to site. Driving of the new bridge pilings is scheduled to begin on Monday, April 9th, and is likely to continue for the next 12 to 15 days. During this time, a total of 62 steel pilings will be hammered into the underlying soil and bedrock (31 piles for each side of the bridge). The contractor will begin work on the east side of the new bridge, with installation of the west pilings to follow. Pile driving work will generally happen between 7am and 7pm on each day, either six or seven days per week until the work is done. As is typical for this type of operation, pile driving will be quite loud as the equipment hammers the steel pilings into the ground.

During the next few weeks, PSA will continue with removal of the demolished roadway bridge, as well as preparation for remaining stages of the project. At a scheduled construction progress meeting on April 5th, PSA advised that the off-site fabrication of the concrete box culverts is going quite well. The box culvert fabrication should be done by mid- to late-April, in advance of the tentative installation timeframe between mid-May and mid-June. PSA also advised that the off-site fabrication of the concrete bridge girders is going well. The fabrication of this component should be done by mid-May, in advance of the tentative installation timeframe of early-June to early-July. At this time, the project is still scheduled to be complete by the end of August.

The City, PSA, and AMEC continue to monitor traffic along the various detour routes. Minor changes have been made to the original plan (the City has imposed some additional parking restrictions near key intersections). However, the current traffic accommodation plan appears to be working quite well, and the City does not anticipate the need for any major changes to the plan at this time. The City would like to thank everyone for your patience and understanding while navigating the various detour routes during construction.

Over the past few weeks, the City has received numerous requests for the City to install new signs along the bypass routes, and particularly signs to identify pedestrian crossing locations. Citizens are reminded that pedestrians are permitted to cross a roadway at any intersection, unless there is a sign specifically prohibiting that crossing movement. Given the temporary nature of the detours, the City is not intending to install any new pedestrian crossing signs along the detour routes at this time, unless that signage was warranted based on typical traffic volumes (i.e. separate from those that exist as a result of the bridge project detours). In the meantime, pedestrians are asked to be patient as they wait for an opening in traffic before crossing the roadway. If you wish to cross a roadway, indicate your intentions by making eye contact with the drivers, and by using the “Point, Pause, Proceed” technique. At the same time, the City is asking all drivers to be considerate of pedestrians wishing to cross the roadways along the detour routes. (For more information on the “Point, Pause, Proceed” technique, please refer to the Province’s website: http://www.transportation.alberta.ca/3004.htm).

Road Closure Set to Begin Monday March 26th

Posted on March 16, 2018

On Friday, March 16, 2018, the City met with AMEC and PSA to review the upcoming work for Phase 2 of the 48 Avenue Bridge Replacement project. As a result of this meeting, the City has learned that there will be a minor delay to the start of PSA’s construction schedule. Rather than mobilizing to Camrose on Monday, March 19th, PSA will now be mobilizing to site two days later (Wednesday, March 21st) to start setting up signage for the various detour routes. All signage should be in place before the end of the week (Friday, March 23rd), although the road closures for 48 Avenue will not start until Monday, March 26th.

At the same time, City crews will be working next week to install additional signs for the parking restrictions along 50 Street (between 48 Avenue and 47 Avenue, southbound lanes only), as well as along 47 Avenue (between 53 Street and 50 Street, south side of the street only). City crews will also be installing new 4-way stop signs at the intersections of 53 Street & 47 Avenue, as well as at 50 Street and 47 Avenue. These new signs should also be in place prior to the end of next week (Friday, March 23rd). These new signs will remain in place over that weekend (March 24th to March 25th) to allow drivers to adjust to the new conditions, prior to the 48 Avenue closures being imposed on Monday, March 26th. The exact time when the road closure will begin on 48 Avenue is not known, although the closure will like start in mid-morning (~10am).

The City, PSA and AMEC will be monitoring traffic very closely during the first few days and weeks after the 48 Avenue road closure is in place. This monitoring will happen throughout the City, and particularly along the key bypass routes and at key intersections. As the public adjusts their driving habits around the 48 Avenue closure, the City will work with PSA and AMEC to determine if any further changes are needed to the City’s traffic network (i.e. additional parking restrictions, 4-way stops, changes to signals, etc.). After observing conditions for ~2 weeks, the City may make additional changes to improve safety and/or traffic flow throughout the City.

The City would like to thank everyone in advance for your patience and understanding during this time.

Road Closure Coming Soon for the 48 Avenue Bridge Project

Posted on March 13, 2018

The construction schedule for Phase 2 of the 48 Avenue Bridge Replacement project has now been finalized, and final preparations are in place for work to begin.

The City’s contractor (PSA Construction Inc.) is intending to bring their equipment and supplies back into Camrose on March 19th. Starting on March 19th, PSA will set up detour route signage and road closure barricades that will be used over the duration of the project.

PSA anticipates that it will take one to two days to set up all of the necessary detour route signage. Sometime on or around March 20th or 21st, 48 Avenue will be closed to all pedestrian and vehicular traffic between 53 Street and 51 Street. The road closure and detours will be in place until the end of the project in late August 2018.

With the closure of 48 Avenue between mid-March and late-August, all vehicular and pedestrian traffic will need to find alternate routes around the area. Vehicular traffic will be generally directed to other major roadways within the City. Lower volume roadways throughout the City are also expected to see an increase in traffic during the period when 48 Avenue is closed, with those local roadways that are located closer to the closure being expected to see a greater increase in traffic. Non-local traffic will be largely directed to use 68 Street and Camrose Drive, although some non-local traffic is likely to use the remaining routes through the City.

Pedestrians are asked to completely avoid the area. If you are needing to walk between downtown and the areas to the west, please use either the remaining walking bridge across Mirror Lake (between 48A Avenue and the Bill Fowler Centre, northwest of the construction area) or the sidewalks along 47 Avenue (south of the construction area). Pedestrians needing to cross 48 Avenue are encouraged to use either the crossing at the 56 Street flashing lights, or the crossing at the 50 Street signals. Crossing at 53 Street or at 51 Street will likely be banned for some or all of the period during construction.

The City and PSA would like to thank you ahead of time for your understanding and patience during this process. If you have any questions or concerns, feel free to direct them to the Engineering department at 780-672-4428 or at engineer@camrose.ca.

Please refer to the following maps for the recommended detour routes around the construction site. (Click on the graphic for a larger version of the map.)

Map of Recommended Bypass Routes around Bridge Closure

Recommended Bypass Routes near Downtown

Pedestrians are encouraged to use the walking bridge across Mirror Lake (northwest of the construction area) or the sidewalks along 47 Avenue (south of the construction area). To cross 48 Avenue, please use the existing flashers located at 56 Street, or the existing signals at 50 Street.

Phase 2 of the 48 Avenue Bridge Project about to begin

Posted on February 26, 2018

After a brief shutdown over the winter months, preparations are currently underway for the remaining work on the 48 Avenue Bridge Replacement Project to begin.

On February 19th, representatives from the City, PSA and AMEC Foster Wheeler (the City’s consultant) participated in two separate pre-fabrication meetings in the Red Deer / Blackfalds area. The purpose of these meetings was to review the specifications and the approved shop drawings for the girders and box culverts, in order to ensure that the products being delivered to Camrose are the best possible quality. The City and AMEC representatives left both meetings satisfied that the fabricators will do a good job. To ensure a high quality product, AMEC inspectors will be on-site on a regular basis to inspect the pieces before and after concrete is poured. Also, AMEC will conduct a final inspection of all completed concrete pieces before they are shipped to Camrose.

In addition to the pre-fabrication meetings, we have been discussing the likely construction schedule for the upcoming work with PSA and AMEC. PSA will deliver a detailed schedule shortly, at which time we will be able to provide more information to the public. (PSA has indicated that they likely will resume work on this project in mid- to late-March 2018.)

Additionally, PSA recently provided us with a draft traffic accommodation plan, showing how vehicles and pedestrians will be re-routed around the construction site over the coming months. We are currently reviewing that draft plan, and expects to have a final plan to be shared with everyone within the next few weeks.

If you have any specific questions or concerns on this project, feel free to contact our Engineering Department at engineer@camrose.ca or at 780.672.4428.

Below are a few photos from the February 19th pre-fabrication inspection for the concrete box culverts. Note: No photos are provided for the fabrication of the bridge girders, as this work has not yet begun.

AMEC and PSA staff inspecting the rebar frames of two of the box culvert pieces that will be used for this project. The far piece is a full box, and is typical of the box culvert piece that will be installed under the new 48 Avenue roadway. The near piece will be part of the ends of the pedestrian underpass, and will have no roof. Both pieces are currently sitting on one of their open ends. Once the concrete has been poured and set, the pieces will be rotated onto their bases. (Note: The photo was taken before the exterior support walls were in place, so that rebar could be inspected and measured. Framing of the exterior support walls occurred following the inspections, and concrete for the two culvert pieces was poured early the following week.)

48th Avenue Bridge Project Phase 1 Complete!

Posted November 29, 2017

On November 29, 2017 the final on-site meeting for Phase 1 of the 48th Avenue Bridge Replacement Project was held. PSA Construction (the contractor) has now begun to demobilize their equipment from the area before their winter shutdown. The contractor is expected to have their equipment removed by the end of Friday December 1, 2017. Due to the freezing of Mirror Lake, the yellow sediment control curtains used for containing stirred up sediment and debris will remain in the lake until spring.

To date, vegetation has been removed and rock fill material has been placed in Mirror Lake on both sides of 48th Avenue to accommodate the widened and elevated roadway. Large rocks called rip rap have been placed along the edge of the rock fill where the new shoreline of the lake will be. These large rocks are used to prevent erosion of the bank.

Now that the work has been completed on Phase 1 of the project, all traffic restrictions have been removed and 48th Avenue will function as normal for both pedestrians and vehicles over the winter months. Please note that the re-opened sidewalks will be rough in places due to the construction that has taken place. The City asks citizens to please exercise caution when using the sidewalks between 51st and 53rd Street. Once PSA Construction starts their work again in the spring, 48th Avenue between 51st and 53rd Street will be completely closed to both pedestrian and vehicular traffic. At that time, pedestrians and motorists will have to find alternate routes around the project.

Phase 2 of the 48th Avenue Bridge Replacement Project will begin in late March or early April of 2018. During the second phase of the project the existing bridge (along with the pedestrian bridges) will be removed and replaced. At the same time this is being done, the roadway will be raised by as much as 1.5 metres to reduce the “grade” (or steepness) of 48th Avenue heading into downtown. As well, an extra travel lane is being added between 51st and 53rd street in both the Eastbound and Westbound directions. Finally, a pedestrian underpass will be installed under the road to allow users of the trail network to pass underneath 48th Avenue without having to cross at either 51st or 53rd Street. All construction is expected to be complete by the end of August 2018.

Over the coming winter months, PSA Construction, the City, and AMEC Foster Wheeler (the consultants) will be meeting to discuss the proposed schedule for the upcoming work. In the meantime, the bridge girders and the box culverts for the pedestrian underpass will be fabricated and inspected.

48th Avenue Bridge Replacement Project - November Update

Posted November 14, 2017

Despite the recent winter conditions, work on the 48th Avenue Bridge Replacement Project continues to proceed. On Friday November 10, 2017 the City, AMEC Foster Wheeler (the consultants), and PSA Construction (the contractor) met on-site to discuss the remainder of Phase 1 of the project.

At the beginning of November, work on the project came to a temporary halt as wet weather conditions caused Camrose County to implement bans on heavy vehicles travelling on County roads. As a result, PSA Construction’s trucking sub-contractor had to temporarily stop their gravel hauling operations. However, the recent prolonged cold conditions have firmed up the roads and trucking operations were able to resume.

Currently, PSA Construction is continuing to place rock fill material in Mirror Lake to the Northwest of the bridge to accommodate for the widened roadway. To allow for the movement of large trucks in and out of the construction site, the roadway has been reduced to one lane westbound through the 53rd Street intersection. As well, the North sidewalk closure will be extended west to the Mirror Lake Bridge walkway. This means that until further notice, no pedestrians will be allowed to cross 48th Avenue at 53rd Street. Pedestrians can cross between the North and South sidewalks at either 56th Street or 51st Street. The City and PSA Construction would like to thank citizens for their continued patience and co-operation during this time.

The contractor anticipates their work to be completed by the end of November, signaling the end of Phase 1 of the project. Once construction shuts down for the winter months, all pedestrian and vehicular traffic restrictions will be removed and 48th Avenue and the sidewalks will function normally.

Phase 2 of the project will begin in late March or early April 2018, when PSA Construction will completely shut down 48 Avenue between 53rd Street and 51st Street to remove the existing pedestrian and roadway bridges.

48th Avenue South Sidewalk and Eastbound Lanes to be Re-Opened

Posted October 31, 2017

By the end of the workday on October 31, 2017 all eastbound traffic restrictions for the 48th Avenue Bridge Replacement Project will have been removed. Until work restarts in the spring, both lanes travelling eastbound on 48th Avenue will be open for traffic. Along with the lane re-opening, the South sidewalk between 51st and 53rd Street will be re-opened for pedestrians.

Until further notice, the North sidewalk will remain closed, as well as the outside lane for traffic travelling in the westbound direction over the 48th Avenue Bridge. Both of these traffic restrictions will be lifted prior to the project shut-down for the winter. When the project resumes in the spring of 2018, 48th Avenue will be fully closed between 51st and 53rd Street to allow for the removal and replacement of the bridge. Construction is expected to be complete by the end of August 2018.

Please note that once the sidewalks are re-opened, they will be rough in places due to the construction that has taken place. The City asks citizens to please exercise caution when using the sidewalks between 51st and 53rd Street.

48th Avenue Bridge Replacement Project - Update

Posted October 31, 2017

The 48th Avenue Bridge Replacement Project is progressing on schedule. To date, PSA Construction (the contractor) has mostly completed their initial work on the South side of the bridge, and in the upcoming days PSA and the City will clear off the South sidewalks for pedestrians to use once again.

On October 26th, the contractor has moved the sediment control curtains from the South side to the North side of 48th Avenue in order to place fill material in the lake for the widened roadway. These curtains are used to prevent stirred up sediment and debris from spreading throughout the lake. Currently, PSA Construction has completed placing rock fill material along the Northeast corner of the project site, and has begun placing fill material along the Northwest corner. Large rocks (rip rap), used to prevent erosion, have been delivered to the Northeast corner of the bridge and over the next few days will be placed along the new shoreline.

Despite the colder weather forecast starting this week, the contractor will be able to continue placing rock fill material and rip rap until they complete the planned in-lake work for Phase 1. At that time, the City and PSA Construction will work together to clean the sidewalks on the North side of 48th Avenue to re-open these to the public. This will signify the end of Phase 1 of this project, at which time the project will largely shut down until the contractor resumes work in the spring of 2018 (March or April). Phase 2 of the project will include a full closure of 48th Avenue between 51st and 53rd Street to allow the contractor to remove and replace the existing bridge. Once work has been completed for the year, Administration intends to provide a formal update on the project to Council and the public at an upcoming City Council meeting, likely to occur in late November or early December.

48th Ave new south shore

Large rocks (rip rap) placed along the new shoreline on the South side of 48th Avenue. Sediment control curtains have been removed from this side of 48th Avenue, as there is minimal risk of environmental contamination with the remaining work on this side of the project.

 

48th Ave pre-loading

Extra rock fill material has been temporarily placed over the alignment of the future pedestrian trail on the Southeast corner of the project. Because this section of trail is being constructed over the former edge of the lake, it is important to ensure proper compaction of the material. By using a process known as “pre-loading”, the extra rock fill material adds additional weight to the material located under the future trail. This assists with compaction and reduces the risk for future settlement of the base of the walkway after it has been paved next year. This extra rock fill material will be left in place over the winter, but will be removed prior to the construction of the pedestrian underpass and trail next year.

 

48th Ave movement of sediment control curtains

PSA Construction is moving the sediment control curtain under the existing 48th Avenue Bridge. Later that day (October 26th), PSA Construction set up these curtains on the Northwest corner of the project to prevent stirred up sediment from contaminating the rest of the lake.

 

48th Ave fortis connecting power lines

Photo taken from the South side of 48th Avenue (East of the Mirror Lake spillway) looking North. A subcontractor for Fortis Alberta is connecting the existing 3-phase power lines to new underground cables that were directionally drilled under 48th Avenue earlier this month. Once those cables have been connected on both sides, Fortis will deactivate the existing overhead power lines. After that is complete, Public Works will work with Fortis and PSA Construction to temporarily shut down all lanes of traffic along 48th Avenue so that Fortis can cut the existing overhead lines and pull them across 48th Avenue. In total, the anticipated disruption to traffic on 48th Avenue is expected to be less than four minutes. Because 48th Avenue is being raised by as much as 1.5 metres for this project, the existing overhead power lines needed to either be raised or relocated under the roadway. The City decided that burying the wires was the best long-term solution for the City.

48th Avenue Bridge Replacement Project - mid-October Update

Posted on October 24, 2017

On Thursday October 19, 2017 an on-site construction meeting was held for the 48th Avenue Bridge Project. This meeting highlighted the work completed to date, as well as the construction schedule for the upcoming weeks.

Currently, PSA Construction (the contractor) is continuing to place rock fill material in Mirror Lake near the Southwest corner of the bridge. This rock fill material is needed to accommodate for the widened roadway. As well, PSA Construction is now removing vegetation and topsoil from the lake near the Northeast corner of the bridge. In the near future, the contractor will begin placing fill material in the lake to the North of 48th Avenue, finishing in November.

The City would like to remind citizens that currently no pedestrian traffic is allowed on 48th Avenue between 51st and 53rd Street until further notice. We anticipate that the South sidewalk will be re-opened to the public by the end of October. Until that time, pedestrians will need to use the nearby walking bridge connecting 48th Avenue and 48A Avenue near the Bill Fowler Centre (Northwest of the construction site) or the walking trail over the Mirror Lake Spillway (South of the construction site).

48th Ave North Sidewalk and Westbound Lane Closure Starting Monday, October 16th

Posted on October 20, 2017

Starting in the afternoon of Monday October 16, the North sidewalk and outside Westbound lane of 48th Avenue will be closed. This closure will be in addition to the existing South sidewalk and Eastbound lane traffic restrictions.

These new traffic restrictions will extend from 51st Street to 53rd Street. This will allow the contractor, PSA construction, to begin moving their equipment over to the North side of the bridge in preparation for placing rock fill material in the Northern section of Mirror Lake. As a result, both North and South sidewalks will be closed for a short duration while this movement takes place. Once PSA Construction completes their work on the South side of the bridge, the South sidewalk will be re-opened.

48th Avenue Bridge Replacement Project - FAQs 

Posted on October 19, 2017

Recently, the City of Camrose has been receiving many questions regarding the replacement of the 48th Avenue Bridge. Below are answers to some of the more common questions the City has received. If you have any further questions or concerns, feel free to contact the City of Camrose’s Engineering Department at engineer@camrose.ca or at 780.672.4428.

Q: What is happening to the 48th Avenue Bridge?

A: The City of Camrose is replacing the existing 48th Avenue Bridge across Mirror Lake. As part of this work, an extra travel lane is being added in both the Westbound and Eastbound directions. As well, the roadway will be raised by as much as 1.5 metres to reduce the grade (or steepness) of the road heading into downtown. Finally, a new pedestrian underpass will be installed under the road to allow users of the trail network to pass under 48th Avenue instead of having to cross the roadway at either 51st Street or 53rd Street.

Q: When did the City decide to do this work?

A: In late 2009, an inspection of the existing bridge was completed which identified that the bridge was nearing the end of its useful life. Based on that inspection, the City began to plan for the eventual replacement of the bridge before the year 2020. In 2014, the City hired consultant AMEC Foster Wheeler to start looking into options for the new bridge. Between 2014 and 2016, various concepts for the new bridge were investigated. These included the construction of the new bridge at the same location and elevation of the existing bridge, changing the location and/or the elevation of the bridge, adding additional lanes to accommodate for future growth, as well as options for a pedestrian overpass or underpass. After many discussions at public Council meetings, City Council ultimately confirmed the current scope of work on November 21, 2016. Following Council’s direction, Administration worked with AMEC Foster Wheeler to finalize the design for improvements, as well as to prepare tender specifications and drawings. The project was publically tendered in the summer of 2017, with the project ultimately being awarded to PSA Construction Inc. on July 17, 2017.

Q: What is the project budget?

A: Prior to the project being issued for tender, the approved project budget was $8M. However, due to competitive tender pricing, City Council formally reduced the project budget to $6.7M.

Q: When should the project be complete?

A: The contract specifies that all work must be complete by the end of August 2018.

Q: Why is the contractor currently putting so much material into the lake?

A: In order to accommodate the additional lanes of traffic as well as the raised roadway and bridge, the existing road base needed to be built out further into the lake on both the North and South sides of 48th Avenue. The amount of “fill” material required is more at the east end of the lake where the change in the roadway height will be the greatest. The material being placed in the lake was sourced from a City-owned pit, and is being compacted and tested to ensure that it will not settle once the road is constructed at the higher elevation.

Q: Why is the contractor putting large rocks into the lake?

A: These large rocks (called rip rap) are placed at the new shoreline to help prevent erosion of the bank of the new roadway. If these rocks were not installed, the banks of the road would eventually be eroded away by wave action along the lake. The location where the rip rap is being placed is the new shoreline for the roadway. See below for the approximate outline of the new shoreline of the lake.

Approximate shoreline

Q: Will the contractor be working through the winter?

A: No. The contractor is currently completing all of the fill work in the lake, finishing around mid - to late - November. This timeframe was chosen specifically by the contractor so that they can complete the more environmentally sensitive work in the fall when there is less risk of rainfall events. Once the contractor has completed all fall work, construction will stop over the winter months and resume in late March or early April. During the winter, all traffic restrictions will be removed from 48th Avenue allowing all lanes to be used by the public.  The sidewalks along both sides of 48 Avenue will also be open to the public over the winter months.

Q: Wasn’t the project supposed to include a full closure of 48th Avenue?

A: Once the contractor started planning out their work for the fall, they realized that they could complete all of the fall work with only single lane closures. However, once the contractor resumes work in the spring, 48th Avenue will be fully closed to allow for the removal of the existing bridge and the construction of the new bridge and roadway. This replacement will occur between April and August 2017, at which time 48th Avenue will be completely closed between 51st and 53rd Street. At that time, all traffic and pedestrians will need to find alternate routes around the project.

Q: If vehicles cannot use 48th Avenue for the 2018 component of the project, won’t the other roads become really busy?

A: Yes, the City expects traffic volumes on all other major crossings of Camrose Creek to increase. These crossings include Camrose Drive, 44th Avenue, 47th Avenue, Grand Drive, and 54th Avenue. Letters were sent to all property owners along the various bypass routes in late July, advising them of the project and the likely increase in traffic. The City will work with the consultant and contractor to monitor traffic on those bypass routes, and to address any issues as they arise. In the meantime, the City would like to thank all motorists and pedestrians for your cooperation and patience during this project.

48th Avenue Bridge Replacement Project - October Update

Posted on October 4, 2017

On Friday September 29, 2017 the first on-site construction meeting for the 48th Avenue Bridge Replacement Project took place. Some of the key attendees included project heads from PSA Construction (the contractor) and AMEC Foster Wheeler (the consultants), as well as the City’s Director of Engineering and Director of Infrastructure Services. This meeting outlined the work that has been completed thus far, as well as the construction schedule for the upcoming weeks.

To date, the majority of the work has been done on the South side of the bridge within Mirror Lake. Currently, rock fill material has been placed within the lake to accommodate for the widened roadway. While this work is being done, the outside Eastbound lane continues to be closed at all times to allow PSA Construction to work more efficiently. At this time, there have been no environmental or safety incidents reported with the work being done on-site.

Most of the work completed so far has been near the Southeast corner of the bridge. However, during the week of October 2, PSA Construction will begin their work in Mirror Lake near the Southwest corner. When this work begins, motorists should expect additional traffic restrictions and delays, especially for those heading North on 53rd Street near 48th Avenue. During that week PSA Construction will also begin removing vegetation on the North side of the bridge to prepare for fill placement in mid-October. Construction fencing is already in place on the North side of 48th Avenue.

The 48th Avenue Bridge Replacement Project is progressing on schedule. Both the City and PSA Construction would like to thank citizens for their patience and co-operation during this project. Stay tuned for further updates. If you have any questions or concerns, feel free to contact the City of Camrose's Engineering Department at engineer@camrose.ca or at 780.672.4428.

 

48th Avenue Eastbound Lane to Remain Closed in Evenings and on Weekends

Posted on September 26, 2017

On Monday September 25, 2017, the City and PSA Construction, the contractor of the 48th Avenue Bridge Replacement Project, reached an agreement to allow PSA Construction to keep a single lane closed at all times during the fall 2017 stages of this project. This new arrangement will enable PSA Construction to work more efficiently than under the original arrangement in which all barricades needed to be removed in the evenings and on Sundays.

Currently, PSA Construction will have a single Eastbound lane closed between 51st and 53rd Street while work is being done in the South portion of Mirror Lake. Once work begins on the North side of the bridge, the Eastbound lane will be re-opened and the outside Westbound lane will be closed throughout the duration of the 2017 work. Along with these lane closures, the sidewalk will continue to be closed on the side where PSA Construction is working. In mid-November, once PSA Construction finishes their work in Mirror Lake, all barricades will be removed and 48 Avenue will function as normal over the winter. Beginning in early 2018, 48th Avenue will be completely closed between 51st and 53rd street for PSA Construction to remove and replace the bridge.

48th Avenue Bridge Replacement Project - September Update

Posted on September 19, 2017

On Tuesday, September 5, 2017 work began on phase 1 of the 48th Avenue Bridge Replacement Project. This two-phase construction is expected to be completed in August 2018, with a full closure of 48th Avenue between 53rd and 51St Street beginning in early 2018.

Currently, work is progressing on phase 1 of the bridge project. This involves placement of rock and other fill material within Mirror Lake to accommodate for the widened road. The yellow booms within the lake, attached to netting, are required during this placement for a few purposes. These nets were initially placed along the shoreline, and then were stretched out into the lake to move all fish and aquatic life out of the construction area. As well, during construction, the nets will keep all stirred-up sediment from polluting the lake.

During phase 1 of the construction, there will be partial closure of the roadway and the sidewalks. However, no more than one lane will be closed at a time, and the sidewalk closures will occur at the same time as the lane closure. Pedestrians will still be able to travel between 51st and 53rd street at all times during phase 1 using the opposite sidewalk to where the contractor (PSA Construction) is working.

48th Avenue Bridge Replacement Project Update

Posted on August 30, 2017

On Wednesday, August 23, 2017, the 48th Avenue Bridge Replacement Project had its kick-off meeting. Some of the key attendees included project heads from the contractor (PSA Construction) and consultants (AMEC Foster Wheeler), the project manager, the site superintendent, the environmental specialist and the City’s Director of Engineering.

The meeting confirmed the general timeline of the project and other details such as plans regarding the safety of the workers, citizens, and the environment.

Construction will be done in two phases:

Phase 1

  • Involves placement of fill material into Mirror Lake for the widened roadway and other related work will begin on September 5, 2017 and should be completed by mid-November.  During the first few days, the contractor will begin mobilizing equipment into the area. Traffic accommodation signs should be in place for both the Eastbound and Westbound directions.  All roads will be clearly marked.
  • There will be construction from 7 am to 6 pm from Monday to Saturday
  • The construction will begin on the south side of the roadway and then the north side.
  • During this time, there will be partial closure of the roadway, but there will be no more than one lane closed at a time.
  • Due to limited space, it will be difficult for wide loads to cross the construction zone. If possible, wide loads are advised to take an alternate route. The City will be notifying all hauling companies who transport over-dimensional loads to advise them of this work.  This will be done via the Provincial on-line permitting system for over-dimensional vehicles.
  • PSA Construction intends to remove any lane restrictions at the end of each working day so that all lanes along 48 Avenue will be open to the public in the evenings and on Sundays.
  • Sidewalks on either side of 48th Avenue during construction will be closed at the same time as the lane closures, meaning that pedestrians will be able to travel between 53 Street and downtown at all times using either the north or the south sidewalk, whichever is opposite of where PSA Construction is actively working.  Alternately, pedestrians can continue to use other walkways in the area, including the walkway over the spillway at the south end of Mirror Lake, or the pedestrian bridge connecting 48A Avenue and 48 Avenue near the Bill Fowler Centre (west of 53 Street).
  • Once PSA Construction completes their work in mid-November, all traffic restrictions will be removed and 48 Avenue will function as normal over the winter months.

Phase 2

  • Full closures for 48 Avenue will not occur until the second phase of the project begins in early 2018.
  • The exact start date for Phase 2 is currently unknown, as this will depend on weather conditions, but it is tentatively scheduled to begin in late March or early April 2018, and will continue until the construction is complete (August 2018).  During that time, no access along 48 Avenue will be permitted between 53 Street and 51 Street.

After the completion of Phase 1, the City will meet with PSA Construction and AMEC Foster Wheeler in early 2018 to review details for Phase 2 of the project.  The City, PSA Construction, and AMEC Foster Wheeler will be meeting regularly to discuss progress and to address any potential issues that may arise. 

Stay tuned for further updates. The City along with the contractor and consultant are working together to ensure safety and efficiency. If you have any questions or concerns, feel free to contact the City of Camrose’s Engineering department at engineer@camrose.ca or at 780.672.4428.

48 Ave Bridge Replacement Project is Underway

Posted on July 21, 2017

48th Avenue is a major route that links the local and regional transportation network in Camrose. The roadway between 51st Street and 54th Street is the busiest section and with the growing population of Camrose, this section requires improvements to support the growth.

The bridge within this section has served Camrose for over 55 years and has reached the end of its life. Along with replacing the bridge, the project will add an extra lane to both the eastbound and westbound directions to accommodate the anticipated increase in traffic. The future seven lane roadway between 51st and 54st Street will be constructed by extending the acceleration lane on the westbound road. The additional eastbound lane will start from the 53rd Street intersection and taper off before 51st Street.

The 48th Avenue Bridge Replacement and Capacity Improvement project also includes decreasing the slope of the roadway between 51st Street and 53rd Street. The change in slope will increase traffic safety and efficiency.

To improve pedestrian convenience and safety, there will also be a new underground pedestrian bypass constructed near the east side of the lake. The underpass will cross the bridge north to south and allow access between the north Mirror Lake trails and Jubilee Park. 

The design for the project has been finalized, the bids were received on June 15, 2017 and the contract is soon to be awarded. The final accepted budget is $6.7 million which is $1.3 million lower than the original $8 million budget.

The exact dates for construction have not been finalized but the following is the tentative schedule of the construction timeline which will be done in two phases. The first phase is set to begin in mid-August 2017 and end by late October 2017 during which the majority of the work will likely be in Mirror Lake. The second phase is the construction on the bridge and roadway which is planned to start in early April 2018 and go to the end of August 2018. During phase 2, 48th Avenue between 51st Street and 54th Street is expected to be fully closed to allow the removal of the old bridge and the construction of the new bridge and roadway. The detour plan is still tentative, but the City expects that all other crossings such as Camrose Drive, Grand Drive, 44 Avenue, 47 Avenue, and 54 Avenue will become busier.

The City and the selected contractor will work together to provide a safe and efficient detour plan to minimize congestion and inconvenience. Stay tuned for more information about detour plans and updates by visiting our website at www.camrose.ca. If you have any questions or concerns, feel free to contact the City of Camrose Engineering department at engineer@camrose.ca or at 780.672.4428.
