About the Calgary Ring Road and the SWCRR

The Southwest Calgary Ring Road (SWCRR) is a project of the Province of Alberta and is one of the last sections of the Calgary Ring Road, which will circle the city when completed. When the Ring Road is complete, it will provide 101 kilometers of free-flow travel around Calgary and contribute to safe and easy movement of goods and people.

Planning for the Calgary Ring Road began in the 1970s, and the northwest, northeast, and southeast sections of the road (known as Stoney Trail) are completed and in use. Construction on the southwest section is nearing completion and will open to traffic in  2021. 

The SWCRR goes from Highway 8 (near Elbow Springs Golf Course) to Macleod Trail S.E. It consists of 31 kilometres of six and eight-lane divided highway, 14 interchanges, 47 bridges, one road flyover, one railway crossing, one tunnel, and three river crossings over the Elbow River and Fish Creek.

The Government of Alberta is responsible for the design, construction, management and operation of Calgary's Ring Road, while the City of Calgary is responsible for the design and construction of street connections to the SWCRR, road improvements, and intersection improvements, because they are located within city limits.

Southwest Ring Road connection projects

The City of Calgary is responsible for the design and construction of the projects connecting Calgary's road network to the ring road. These City-led projects will accommodate changes to traffic volume and patterns that are expected after the opening of the Southwest Ring Road.

These projects include:

  • Glenmore Trail widening and interchange upgrades
  • Anderson Road widening
  • 90 Avenue and Southland Drive connections
  • Spruce Meadows Way widening
  • 162 Avenue connection
  • Westhills Way
