Another Update from the Bridge Construction

Posted on August 13, 2018 at 10:52 AM by Ashton Ford

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.

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.

The bolts that are sticking up from the girder’s curb will support the roadway guardrail that protects pedestrians on the south walkway.

Another Update on the Bridge Construction

Posted on July 30, 2018 at 8:40 AM by Ashton Ford

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.

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.

Minor Delays Expected for 48 Avenue Bridge Replacement Project

Posted on July 30, 2018 at 8:30 AM by Ashton Ford

Unfortunately, it looks as though the completion date for the 48 Avenue Bridge Replacement project will be delayed until early to mid-October.

During an on-site meeting in late June 2018, the City highlighted a possible issue with the original design. Upon investigation in July, the project team determined that there was in fact a communication error related to the design of the lane widths for 48 Avenue. Unfortunately, this issue was not identified and fixed before the design was finalized in 2017. When originally designed by AMEC, each lane was set at 3.7 metres; this included the driving lane, as well as a 0.3 metre wide roadway gutter for the curb lanes. AMEC designed the project this way, as this standard is used in some other municipalities. The standard that the City of Camrose has typically uses for all sections along 48 Avenue is to have 3.7 metre lane widths, with an additional 0.5 metres for each roadway gutter. The City uses this standard on all truck routes within Camrose and particularly along 48 Avenue, which is the City’s designated route for over-width vehicles. This standard gives users some extra room to account for the fact that drivers do not tend to drive within the gutter, or near the curb. Without this extra room for the gutters included, the constructed roadway under the original design would be approximately 2 metres narrower than desired (0.5 metres per location along the inside and outside edges for both the eastbound and westbound lanes).

Over the past month, the project team has been working together to determine various options to find a solution to this issue. Some of the considered solutions were to keep a narrower roadway through the project, to widen the bridge structure, and to reduce the widths and/or eliminate the pedestrian walkways that will run along either side of 48 Avenue. Ultimately, the City decided to reduce the width of the south pedestrian trail from 4 metres to 2 metres. This will allow for the proper roadway lane widths, and still allow for a reasonable pedestrian pathway. Previously, the sidewalks along 48 Avenue were 1.8 metres wide; therefore the addition of a 2 metre pathway on the south side will still easily accommodate the local foot traffic. Additionally, the project still maintains a 4 metre wide pathway across the bridge on the north side of 48 Avenue.

In order to complete this change, PSA will need to remove and reinstall two of the recently installed girders, in order to narrow the southern walkway. Similarly some miscellaneous infrastructure, like the new signal poles at 53 Street will need to be relocated. See below for a visual representation of the changes being made to the girders.

This change is estimated to delay the project an additional three to four weeks, putting the predicted completion date in early to mid-October. There should be no impact to the overall project budget, as the City included a “project contingency” to account for potential changes like this when City Council originally approved the budget. More information will become available as the City continues to conference with PSA and AMEC, and further updates will be made as the information is shared.

The City of Camrose would like to continue to thank everyone for their patience and understanding. If anyone has questions, regarding the project as a whole, or this design change specifically, please contact the City of Camrose Engineering department at engineer@camrose.ca or at 780.672.4428.

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

new_plan_image
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.
