South West Calgary Ring Road

Ledcor was a fully integrated partner of KGL Constructors, the joint venture partnership between Kiewit, Graham, and Ledcor responsible to design, build, finance, operate and maintain the Southwest Calgary Ring Road, with Parsons as the lead designer. This large Public-Private-Partnership (P3) project for Alberta Transportation, was the second last section of a 101 km free-flow highway around the City of Calgary and can accommodate traffic volumes up to 100,000 vehicles per day. 

The project included 31 kilometres of six and eight-lane divided highway, 14 interchanges, 46 bridges, a precast arch tunnel, three river crossings, and two river realignments at Elbow River and Fish Creek. To accomplish this the project team completed 15 million m3 of earthworks, placed 3.2 million tonnes of aggregate, 1 million tonnes of asphalt, and over 85,000 m3 of concrete. A large portion of the work was self-performed including the structures, drainage, and granular placement scopes.

The project included both greenfield and brownfield construction in constricted work sites near live traffic, railways, and environmentally sensitive areas so close coordination with key stakeholders such as Tsuut’ina First Nation, CP Rail, the City of Calgary and Alberta Environment was critical to the project’s success. In October of 2020 and 2021 the road was successfully open to traffic, meeting the key milestones for traffic availability.
