TransCanada Highway – Sarcee Trail Interchange Update

Though construction is still ongoing, Trinity is pleased to announce that the TransCanada Highway (TCH) – Sarcee Trail Interchange project is moving towards completion.
Traffic is now temporarily shifted to the outside ramps until the construction work in the center is completed. This includes:

  • The pedestrian underpass
All remaining underground utility work
  • The center roundabout

  • Access to Medicine Hill and adjacent communities.

The north side of TransCanada Highway is also still underway, including finishing an improved westbound entrance ramp.
Due to the construction, there will be rotating short duration lane closures and traffic delays. These closures and delays will facilitate the final paving and road marking work throughout the month of August. All ramps and accesses are tentatively planned to be open by late August.
Our construction teams work diligently to minimalize the lane closures as much as possible to ensure the least amount of inconvenience to Calgary commuters.
We will have access to the Medicine Hill community open to the public by late 2018.

Bridge Rehabilitation Temporary Conditions

Following the completion of the current interchange work in August, the roadway over the existing Sarcee Trail overpass bridge will have some temporary conditions in place. These conditions will be limited to the bridge deck and its approaches, and consist of:

  • Two lanes for all southbound traffic
  • One lane for northbound traffic into Bowness, and
  • One lane for northbound traffic destined for the westbound TransCanada Highway.

This temporary condition will be in place until The City commences work on the planned rehabilitation project for this bridge. This work is tentatively scheduled for the 2018 construction season and The City will undertake additional temporary traffic accommodation measures to facilitate the work during that time.
We want to keep everyone informed on any updates to the project, so once more definitive dates and further temporary traffic accommodation measures are determined, information will be sent out.
