Stoney Trail - Southwest Calgary Ring Road

The final leg of the Calgary Ring Road, currently known as the Southwest Calgary Ring Road, but also widely referred to as the Sarcee Trail Extension, is still in the initial planning and public consultation stages. The original proposed route ran from approximately the intersection of Sarcee Trail and Glenmore Trail (Highway 8), south through the Tsuu T'ina First Nation to eventually reach Spruce Meadows Trail in the south of the city. Plans called for the road to be initially built as a 4-6 lane expressway with the ability to easily upgrade the corridor to the 'ultimate' stage (to be completed by 2035) as a 16 lane freeway with express and collector lanes. However, the routing was rejected by the Tsuu T'ina First Nation on June 30, 2009. Despite indications from the band that they would like to reopen negotiations, the province has shown little interest. As an alternative, the City of Calgary proposed constructing an interchange at the intersection of Glenmore Trail and 37 Street SW. Construction of phase one of the interchange began in May 2010 and opened to traffic in September 2010.
