Maintained by Alberta Transportation, Deerfoot Trail is the major north/south transportation route through the City of Calgary and is part of the North/South Trade Corridor. Since the 1970s when most of the road was constructed, Calgary’s population has doubled and traffic volumes continue to increase. Today it is the busiest road in Alberta and serves more than 190,000 vehicles per day.

Project details

In conjunction with Alberta Transportation, the City of Calgary completed the Deerfoot Trail Corridor Study (PDF, 7.8 MB) in December 2020.

Improvements are planned for:

  • 64 Avenue NE & McKnight Boulevard
  • 11 Street NE
  • 64 Avenue NE & McKnight Boulevard
  • Memorial Drive & 17 Avenue SE
  • Glenmore Trail
  • Southland Drive & Anderson Road / Bow Bottom Trail

In July 2022, the government announced it was cancelling the public-private partnership (P3) approach to upgrading Deerfoot Trail due to escalating costs. Improvements to Deerfoot Trail will now be completed in smaller bundles, prioritizing work on the most congested areas of the highway.

In August 2022, Alberta Transportation posted the tender for work between 64 Avenue and McKnight Boulevard. Construction on this project will occur in 2023. 


Deerfoot Trail improvements move ahead (August 22, 2022)
