Stoney Trail

Stoney Trail is a 69km freeway in Calgary, Alberta, Canada. Signed as Highway 201, it is a ring road that is approximately 70% complete, serving as an important bypass around the city and an alternate route to the congested Highway 1 (Trans-Canada Highway) and Highway 2 (Deerfoot Trail). Stoney Trail begins in the city's northwest at Highway 1 near Canada Olympic Park, running north across the Bow River and Crowchild Trail. It winds through neighbourhoods of northwest Calgary to Deerfoot Trail and the Queen Elizabeth II Highway. Turning south, the freeway again intersects Highway 1, crosses Glenmore Trail, and curves west at the neighbourhood of Mahogany. Beyond a second major interchange with Deerfoot Trail, it descends across the Bow River and ends at Macleod Trail in the city's southeast.The "Stoney" name is derived from Alberta's Nakoda First Nation; the freeway is one of several major thoroughfares in Calgary that bear Aboriginal names. Plans for the route were developed at a similar time as those for Anthony Henday Drive, a completed ring road that encircles Edmonton. Construction first began on the northwest leg as an expressway in the 1990s, incrementally extending east before two public–private partnership (P3) projects completed the northeast and southeast sections of the ring in 2009 and 2013, respectively. After right of way was acquired from the Tsuu T'ina Nation in 2013, work began in 2016 to complete an additional section of the ring effectively extending Sarcee Trail south across the Elbow River to Highway 22X. This section will be named Tsuut’ina Trail and is slated to fully open by October 1, 2021.
