Project overview

Alberta Transportation and Economic Corridors (TEC) is undertaking improvements to Deerfoot Trail.

Deerfoot Trail is Alberta’s busiest freeway and sees over 180,000 vehicles per day in some sections. It is a critical component of Calgary’s transportation network for both commuter travel and goods movement. Since Deerfoot Trail was initially constructed in the 1970s, Calgary’s population has doubled, more people have access to vehicles, and traffic volumes have continued to increase. 

The improvements will add additional lanes along Deerfoot Trail as well as improve safety and reliability for drivers. This work supports Calgary’s current traffic volumes and sets The City up for future population growth and projected traffic volumes. 

Though Deerfoot Trail runs through the heart of Calgary, it is operated and maintained by The Province. 

As with any construction project, there will be impacts to the public throughout construction. The City of Calgary will work closely with The Province to limit the impacts of construction to residents, businesses, and commuters wherever possible. 

Who is responsible for maintaining Deerfoot Trail during construction?

Carmacks Enterprises is the highway maintenance contractor responsible for the ongoing maintenance of Deerfoot Trail. Within each construction project, the contractor will work closely with Carmacks to ensure the area is adequately maintained. 

Contact information for Carmacks can be found here.

How is the City working with the Province to mitigate impacts to the public? 

The City will primarily support the Province in mobility communications and traffic adjustments. This includes coordinating closely with the Mobility Operations Centre (MOC) and the Signals Engineering team to monitor traffic operations and make necessary adjustments to traffic signals.

Where can I find traffic updates?

TEC’s project website will be updated as traffic updates and impacts are known.

For updates regarding City roadways please refer to the City of Calgary’s Traffic Information Map.

Will bus routes be affected?

Calgary transit has some bus routes on Deerfoot Trail as well as adjacent roads that may be impacted periodically throughout construction. will be updated if and when transit routes are affected.
