Bow River Pathway Paving Complete

Last week the new segment of the Bow River Pathway was temporarily closed for paving. We appreciate your patience and are pleased to report that the new pathway is now open.

Update on Scenic Acres Link N.W. Exit Ramp Bridge

Earlier this year, the bridge abutments were completed and girders were installed on the exit ramp bridge over Scenic Acres Link N.W.

Since the girders were placed in May, the overhang brackets have been installed and the bridge deck formwork and diaphragm installations are nearly complete. Work on the bridge – including wingwalls and bridge approach structures – will continue into the 2021 construction season.

Overnight Work on Valley Ridge Boulevard N.W. Interchange

Starting on Wednesday, September 16 until Friday, September 25, crews will be working 24 hours a day to backfill two areas to connect the temporary bridge over Valley Ridge Boulevard N.W. with the new bridge to the east. This is required for the Trans-Canada Highway detour while the other two bridges are being constructed.

To mitigate noise and disruption during the night, gravel will be delivered and stockpiled during the day, back-up alarms will be turned off and light towers will face south and away from nearby residences.

Paving on Valley Ridge Boulevard N.W.

Paving is getting underway on portions of the Valley Ridge Boulevard N.W. interchange, which is a big milestone for the project and signals the completion of some roads. Laying asphalt sometimes produces strong odours from the materials used. The smell typically dissipates soon after the asphalt is laid.

Getting Connected

With the girders for both spans now in place on this mainline Stoney Trail bridge, the formwork is being installed for the bridge deck and the pier diaphragm, which connects the girders to the centre pier cap.


Wingwalls are located on both ends of a bridge abutment to retain the earth that will provide the approach to the bridge deck.
