Constructing the missing link

The Calgary Ring Road circles the City of Calgary, serving the growing city’s population while accommodating more than 50 years of forecasted traffic growth. The goal for the high-speed freeway was to improve safety, connect to key provincial highways, and provide access to other city roads—all supporting the efficient flow of motorists and goods along this critical north-south truck route.

The Southeast Stoney Trail (SEST), a key section of the looping highway, was delivered through a public-private partnership. The project involved the design, construction, operations support, maintenance, and rehabilitation of 25 kilometres of six-lane roadway, nine interchanges, one road flyover, two rail flyovers, and 27 bridge structures.

As design consultant, our multidisciplinary team was responsible for preliminary and detailed designs of transportation, structural, electrical, and utility components along a 13-kilometre segment of the SEST route. Our part of the six-lane freeway design included two systems interchanges, four service interchanges, and 13 bridge structures. Plus more than 14 million cubic metres of earthwork and 300,000 tons of asphalt.

Bringing relief to drivers from the city’s southern quadrant as well as travelers headed into and around the city, this project is a boon to commercial motorists and public users alike. Albertans can now take the Calgary Ring Road from Macleod Trail on the city’s south side, along the eastern border and around the north, connecting with Highway 1 toward Banff.
