Deerfoot Trail is Alberta’s busiest freeway and a critical component of Calgary’s transportation network for both commuter travel and goods movement.
Much of the road was constructed in the 1970s. Since then, Calgary’s population has doubled, more people have access to vehicles and traffic volumes continue to increase. In 2019, the average weekday traffic volumes were 93,000 at Stoney Trail SE and 190,000 at Memorial Drive. Improvements are needed to bring the road’s capacity closer to the current and projected traffic demands, as well as improve the safety and reliability of this important transportation corridor.
The Government of Alberta is investing $210 million to upgrade the highest priority areas identified in the 2020 Deerfoot Trail Corridor Study. The improvements focus on increasing road capacity and reducing ‘turbulence’ caused by vehicles weaving to get on and off the freeway.
Similar to the Southwest Calgary Ring Road, the improvements will be delivered using a Public Private Partnership (P3) contract structure, which will require the successful proponent to design, build, finance, operate and maintain the infrastructure for the next 30 years.
