Stoney Trail at Shaganappi Trail interchange

Project update - November 2021

Construction of the Shaganappi Trail bridge supports and centre pier is now complete, and the bridge girders will be installed this winter.

Road work, utility, and streetlight installations north and south of Stoney Trail are complete for this season, and over the winter months crews will be working on the traffic signal at the Shaganappi Trail and Hidden Valley Drive N.W. intersection.

Crews will return in the spring of 2022 to continue the road works for the interchange.

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


  • 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.
