Calgarians celebrated the opening of the Southeast Stoney Trail freeway on November 22. The new highway provides motorists with 70 kilometres of free-flowing road with no traffic lights and a speed limit of 100 kilometres per hour.

Interchanges along the highway were opened in a domino fashion in both directions, starting southbound with Highway 22 X/Stoney Trail and 88 Street SE, and finishing with Peigan Trail. The east-west stretch was already opened.

Seventy per cent of the ring road around Calgary is now completed, with just the southwest portion remaining.

The $769-million Southeast Stoney Trail project has been under construction for three years and is the largest single highway project in Alberta’s history. It involved building nine interchanges, three flyovers and 27 bridge structures.

It was also the province’s largest P3 transportation project, contracted to Chinook Roads Partnership, a joint venture between SNC-Lavalin and Acciona S.A.. They have a 30-year contract to maintain the highway as well as a 12-kilometre section of Deerfoot Trail that branches off it.
