Alberta Transportation and Economic Corridors: Bow Valley Gap Wildlife Overpass

In partnership with DIALOG

The Trans-Canada Highway east of Banff National Park restricts wildlife movement in the Bow Valley and has experienced many collisions involving deer, elk and bears. In response, Alberta Transportation and Economic Corridors built the Bow Valley Gap Wildlife Overpass – the first such structure in the province outside national parks. Its design visually blends into the landscape, uses native vegetation to encourage use, and protects existing plants and habitat connectivity. Landscaping and fencing direct wildlife away from the highway and toward the overpass, while the width of the overpass and soil berms along its edges attenuate the impacts of traffic noise and headlights. Animal movements were tracked during construction to ensure no species were negatively impacted, and surveillance revealed that some animals started using the overpass a year before it was complete. Based on similar structures in Alberta, the overpass is expected to prevent up to 80% of local collisions with large mammals.
