Calgary Ring Road

Circle is two-thirds done

The Government of Alberta and The City of Calgary began planning for the Calgary Ring Road in the 1970s. During the 1980s and 1990s, the province purchased most of the lands needed for the Transportation Utility Corridor around Calgary where the ring road would be built. With the northwest, northeast and southeast sections in operation – known collectively as Stoney Trail – the ring road now provides motorists with 70 kilometres of free-flow travel. It connects Highway 2 (Deerfoot Trail) in the south to Highway 1 (TransCanada Highway) towards Banff.

Completing the ring
Completing the full 101 kilometres of the Calgary Ring Road is a priority for Alberta Transportation, and is an investment in the long-term safe and efficient movement of goods and people in and around Calgary. The ring road will also provide improved market access across Calgary, the province, Canada and to foreign ports.


31 kilometres to go
The construction of this last 31-kilometre stretch of the Calgary Ring Road continues to move forward. When complete, this final section of the ring road will consist of:
  • 66 bridges;
  • 31 kilometres of six- and eight-lane divided highway;
  • 20 interchanges, 2 underpasses; and
  • Several river crossings.
Work to date
  • Alberta Transportation started long-term functional planning studies in 2003, with studies covering three legs.
  • The Technical Review Committees for the studies included representatives from the City of Calgary, Rocky View County, the MD of Foothills and the Tsuu T’ina Nation.
  • Several public consultation meetings were held between 2005 and 2009 before the studies were completed and amalgamated in 2011.

  • In November, 2013, the Government of Alberta and the Tsuu T’ina Nation signed an historic land transfer agreement which paved the way for completion of the future ring road. Representatives from the Tsuu T’ina Nation, the Government of Alberta and the federal government are working together to fulfill the agreement.
  • The transfer of lands is proceeding well and the government is now focussing on the delivery of the southwest section of the ring road first.
  • Transportation is investigating using the Public Private Partnership (P3) procurement process to deliver the final segment, planned for construction as two projects – the Southwest Calgary Ring Road (SWCRR) and the West Calgary Ring Road (WCRR). To date, the province has saved about $2 billion by using P3 contracts to build a total of five segments of the Edmonton and Calgary Ring Roads.
