T CH/Sarcee

Sarcee Interchange on track for full completion by fall 2017

Construction on the Sarcee Trail – TransCanada Highway (TCH) Interchange is ongoing with no permanent full road closures anticipated over the winter season.


Over the winter there will be a decrease of roadwork activity and temporary lane closures will be minimized until the spring.


The new northbound to eastbound ramp is now open. The new east and west bridges require only the finishing surface treatment and are expected to open with the northbound and southbound by-pass ramps in spring 2017.


Full project completion is targeting Fall 2017.

TCH – Sarcee Interchange Construction Update

Higher than average rainfall has slowed progress on the interchange work, so construction is now about 30 per cent complete. However, work is ongoing with no major road closures or detours anticipated in the near future. The current temporary traffic detours will be in place until end of this construction season. Some temporary, short-term shoulder and lane closures are expected to occur intermittently.
The current construction schedule is being evaluated to determine if there are any impacts to the key completion dates. The schedule is weather dependent and we will continue to provide public updates as we progress.

Improving traffic flow

Improvements proposed for the Trans Canada Highway and Sarcee Trail Interchange will facilitate access to Trinity Hills development and improve the functionality of the existing interchange.

Trinity to fund improvements at TransCanada Highway and Sarcee Trail interchange

Trinity Development Group is working with the City of Calgary to fund and construct improvements to the interchange at Sarcee Trail and TransCanada Highway.
A key goal of the project improvements is to improve flow through of traffic in the area, and ensure that the Trinity Hills project does not impact traffic volumes and commute times for commuters living in surrounding areas. The changes will also provide access to the Trinity Hills development.
These interchange improvements will also eliminate conflict points, increasing safety for all drivers.

Included in the scope of the project are construction of two roadway bridge structures, a pedestrian underpass, and retaining walls. At the same time we will include rehabilitation of existing bridges and related earthworks, roadworks and utility works.

Traffic improvements mean uninterrupted traffic flow for commuters

The improvements to the TransCanada Highway/Sarcee Trail interchange are strategically designed to separate the higher volume ‘regional’ traffic movements from the ‘local traffic’ requiring access to the new development and adjacent communities. This design will allow those using the interchange to drive directly through without being impeded or impacted by the local community traffic.

Bowdale Crescent traffic changes

In response to discussions with the community of Wilson Gardens, regarding the current construction access onto Sarcee Trail – TCH , the project team has made the following improvments:

  • The currently designated community exit location was relocated to the final, ultimate location and allows residents to leave the community without conflicting with vehicles entering the community as of December 2, 2016. The community entrance location will remain in the same location.
  • A deceleration lane will be added to the current ‘U-turn’ on Sarcee to ensure normal flow of traffic is maintained while allowing vehicles to slowly leave the main roadway prior to accessing the turning area.




Minimizing Construction Impacts

The majority of the interchange work will take place off the existing roadways. This strategy will minimize the need for any full road closures or major detours. We anticipate there may be a need for short duration lane closures and speed reductions as we complete ramp connections, the existing bridge rehabilitation, and other features throughout the project.
Our goal is to minimize traffic impacts as much as possible.

The TCH-Sarcee Interchange is a joint project between The City of Calgary and Trinity. For continued updates on the project, please sign up for the newsletter below.

Wilson Gardens

The Wilson Gardens exit to southbound Sarcee Trail will be closed as of April 21st through the duration of the construction.

Bridge Detours

As of May 1, drivers will notice a small shift on the northbound to eastbound ramp to a 150-metre stretch of pavement. This will allow work to begin on the east bridge. The speed limit on this ramp will continue to be 30 km/hour. However, construction zone speed penalties will apply.
As of May 14, drivers will notice a small shift on the eastbound to southbound ramp to a 100-metre stretch of pavement that will allow work to begin on a new ramp. The speed limit on this ramp will be 30 km/hour and construction zone speed penalties will apply.
