Loop Bridge Replacement

Crowsnest Highway, East Kootenay C, BC, Canada

The Crowsnest Highway is a major arterial link between southern British Columbia and Alberta in Canada, and Washington State, Idaho, and Montana in the United States. Traffic on this section near Sparwood was constrained by the close proximity of an at-grade crossing of the Canadian Pacific Railway, an intersection with Corbin Road (local access), utility corridors and the existing narrow Loop Bridge over Michel Creek. Klohn Crippen was retained by the British Columbia Ministry of Transportation to prepare alternative solutions and to design the preferred option which required two new bridges and realignment of the intersection. Most of the services, including highway and bridge design, and geotechnical and environmental services, were provided by in-house staff.
