Phase 2 of 48 Avenue Bridge Project Going Well so Far

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:

Here are a few photos taken from the first few weeks of Phase 2 of this project:

Bridge 3

 March 28th – PSA in the process of removing the roadway bridge.  The pedestrian bridges had already been removed, and are seen toward the right side of the photo (behind the white storage container).  PSA delivered the pedestrian bridges to a City storage facility, where they can be repurposed for a future installation elsewhere in the City (locations to be determined).
Bridge 4

April 5th – Concrete pieces and rebar from the old roadway bridge.  This material will be removed in the coming days.  All concrete and asphalt will be sent to the City’s concrete recycling centre located near the landfill, where it can be crushed and repurposed for future projects.
Bridge 5

April 5th – AMEC and PSA staff walking across the last section of the old roadway bridge during a scheduled construction inspection.  This remaining section will be removed by Monday, April 9th, at which time the pile driving contractor will begin their work on the east side of the new bridge.
