Stoney Trail at Shaganappi Trail interchange

Project update - May 2022

Upcoming lane closures: Shaganappi Trail Interchange

Traffic signal installation at the Shaganappi Trail / Hidden Valley Drive N.W. intersection is underway and crews are planning to shift traffic to the next stage detour. Next week the following detours and temporary speed limit reductions will be in place while crews work on the bridge deck:

  • May 9, 2022 from 10 p.m. to 5 a.m. the two right hand lanes on westbound Stoney Trail at Shaganappi Trail N.W. will be closed.
  • May 10, 2022 from 10 p.m. to 5 a.m. the two left hand lanes on westbound Stoney Trail at Shaganappi Trail N.W. will be closed.
  • May 11, 2022 from 10 p.m. to 5 a.m. the two right hand lanes on eastbound Stoney Trail at Shaganappi Trail N.W. will be closed.
  • May 12, 2022 from 10 p.m. to 5 a.m. the two left hand lanes on eastbound Stoney Trail at Shaganappi Trail N.W. will be closed.

The speed limit on Shaganappi Trail north and south of Stoney Trail will be reduced to 50 km/h while crews are working.

You can see the responses to questions asked during the design phase of the Stoney Trail / Shaganappi Trail interchange here.

Impacts:

  • The speed limit on Shaganappi Trail north and south of Stoney Trail will be reduced to 50 km/h overnight between May 9 and 12, 2022. 
  • The speed limit of Stoney Trail close to construction area may be reduced to 80 km/h during construction.
  • The speed limit on Shaganappi Trail north and south of Stoney Trail has been reduced to 50 km/h. 

The existing interchange at Stoney Trail and Shaganappi Trail N.W. was constructed in 2006-2007 and is three lanes wide, with two lanes southbound and a single lane northbound. This project will upgrade the interchange by building a second three-lane bridge adjacent to the existing north-south bridge, providing three travel lanes in each direction once completed. The final interchange will provide a multi-use pathway which will connect to pathways on both the north and south sides of Stoney Trail.

In addition to upgrading the interchange, this project also includes an upgrade to the Shaganappi Trail/Hidden Valley Drive intersection to facilitate better access to and from the community.
