Trans-Canada Highway Reduced to One Lane Nightly

From 10 pm to 6 am each night between Monday, June 29 and Thursday, July 2, traffic will be reduced to one lane in each direction on the Trans-Canada Highway east and west of Stoney Trail. These closures are needed to install the overhang brackets to support the bridge deck formwork.

Controlled Blasting Resumes July 6

A reminder that controlled blasting will resume on Monday, July 6. For more information, please visit > Controlled Blasting.

Trans-Canada Highway/Stoney Trail Interchange

Liners are constructed from low permeability materials, such as clay, geomembrane or concrete, and reduce the likelihood that pollutants in stormwater will reach ground water by slowing infiltration from the stormpond into the ground.

Trans-Canada Highway/Valley Ridge Boulevard N.W. Interchange

With integral bridge abutments (as shown below), the foundation piles are sometimes driven through vertical Corrugated Steel Pipe (CSP) casings. The CSP sleeves and the styrofoam beads (in bags) poured around the piles allow the piles to move as the bridge expands and contracts.

South Project Contract Awarded

Last week, the contract for the South project was awarded to Calgary Safelink Partners for $277 million. Some preliminary work will begin this summer, with the majority of construction starting in the Spring of 2021. The completion date for the South project has been updated to 2024 to accommodate the regulatory process that was required to relocate the ENMAX transmission lines, as well as considerations for the COVID-19 pandemic.

Detour on Old Banff Coach Road SW for Utility Work

From late June to mid-July, there will be a detour on Old Banff Coach Road, east of 101 Street SW, to accommodate relocating a City of Calgary potable water feedermain. The detour will affect traffic in both directions and the speed limit will be reduced to 30 km/h through the area.
