Building Northeast Stoney Trail

The 13-mile Northeast Stoney Trail (NEST), is a northeast portion of a ring road around Calgary. The road extends from Deerfoot Trail, the main north-south route through Calgary, south to 17 Avenue SE. The project included 23 bridge structures and six interchanges, including one major interchange at Deerfoot Trail and one at the Trans-Canada Highway 1.

According to the Alberta government, Deerfoot Trail is the heaviest traveled road in the entire Province of Alberta, with an estimated 30,000 to 40,000 vehicles expected to use the new ring road each day. Under the P3 financing model, the road was finished on time and on budget.

The Public Private Partnership project for the Province of Alberta was developed by Bilfinger Berger BOT, and the project was designed and built by Stoney Trail Constructors, a joint venture led by Flatiron.
