TransCanada Highway & Sarcee Trail Interchange

  • Share

​Construction is starting on the interchange this spring for the development at the base of the east Paskapoo Slopes. As a requirement of Council, this interchange just south of the TransCanada Highway (TCH) on Sarcee Trail provides access to the new development and ensures uninterrupted traffic flow for local and commuter travel. There were two public information sessions held at the end of January for residents to see these designs and speak with the project team.  Feedback was positive and residents were encouraged to learn that there would be a continuous flow of traffic on Sarcee Trail at current speed limits.  East/west and north/south regional traffic flow will continue to operate as it does today and drivers will not be impeded by local traffic.  The Sarcee Trail bridge deck over the TCH will be rehabilitated and reconfigured for better safety and efficiency; the west bound ramp on and off of the TCH will also be upgraded.  Please reference the diagram below.

A condition of the West Springs Cougar Ridge Community Association support for this development was that priority consideration be given to how pedestrian and cycle traffic and connectivity could be made better through this development. The interchange provides access for local communities, a roundabout for easy entry and exit into the new development, including a pedestrian underpass, as well as a regional network pathway connection.

We negotiated that the developer be responsible for all of the costs associated with the development of access at Sarcee Trail, including the new ramps, bridges, and the roundabout. This negotiation also included the cost of building a pedestrian bridge connecting the development over the Trans-Canada Highway just west of Sarcee Trail to Bowness, and half the cost of an underpass which will connect to Edworthy Park and the Bow River pathway, both of which may be used by cyclists and pedestrians. Detailed design is approaching final stages and construction is expected to be functionally complete by the end of 2016, with all final work finished by summer 2017. Most of the construction will be done off of the major roads which alleviates the need for road closures or significant detours. For detailed information and visuals, please visit
