Icefields Interchange Design-Build

Location: Lake Louise, Alberta

The project consisted of upgrading the existing Icefields Parkway Interchange, located at the junction of Highway 93 and the Trans-Canada Highway, near Lake Louise, in Banff National Park, Alberta.

This design-build project included the design and construction of a new interchange overpass structure, new ramps, widening and twinning of the Trans-Canada Highway, and the design and construction of a new bridge over the Bow River at the western end of the project. At the eastern end of the project, the road alignment connects to the existing twinned Trans-Canada Highway. Within the project limits, the twinned highway passes between the support piers of the existing 30-metre high CPR overpass structure.

The work also entailed: the demolition of the existing interchange overpass structure; the drilling, blasting, and excavation of approximately 250,000 tonnes of rock; the supply and placement of 132,500 tonnes of granular materials; 35,000 tonnes of asphalt pavement; street lighting; permanent roadway signage; culvert installation; landscaping; fencing; and traffic accommodation all to be accomplished while maintaining the existing two-lane Trans-Canada Highway traffic movements.
