Southeast Stoney Trail

In 2010, SNC-Lavalin’s Chinook Roads Partnership was awarded a landmark contract by Alberta Transportation to design, build, operate, maintain and partially finance the Southeast Stoney Trail (SEST) Highway. Now complete, the project includes 25 kilometres of six-lane road, nine interchanges, one road flyover, two rail flyovers and 27 bridge structures. It’s no wonder SEST is considered the second largest highway project in Alberta’s history in terms of scope. 

A Vital Highway

SEST is a part of the wider 70-km Stoney Trail Ring Road, a vital component of the provincial highway network which supports Alberta’s vision to provide safe, accessible, free-flowing travel in and around the region. Stoney Trail Ring Road helps improve travel times and reduce congestion for drivers by enhancing accessibility to and from the communities of southeast Calgary. An example is the convenient access the road provides to the new 300-bed South Health Campus, the largest hospital in Alberta and one of the most leading-edge healthcare facilities in western Canada. 

A Focus on Long-Term Safety

Managed as a public private partnership, the agreement includes a 30-year operations and maintenance contract for the road, as well as other existing infrastructure. With Calgary’s sometimes challenging winter driving conditions, the operations and maintenance team will focus on making SEST one of the safest and well maintained highways of its kind all year round.
