Southeast Stoney Trail P3

A roadway designed to connect a community

Calgary, Alberta

When completed, the Calgary Ring Road will circle the growing city of Calgary and accommodate more than 50 years of forecasted traffic growth. The high speed freeway will improve safety, connections to key provincial highways, and 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) is a key section of the looping highway. Delivered through a Public-Private Partnership, the project involved the design, construction, operations, maintenance, and rehabilitation of 25 kilometers of six-lane roadway, nine interchanges, one road flyover, two rail flyovers, and 27 bridge structures.

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

This project brings relief to drivers from the city's southern quadrant, travelers heading into and around the city and commercial motorists moving goods to market. 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.
