Description
Phase 4 of the Kicking Horse Canyon Project lies between the previously-completed Phase 3 West (Golden Hill to West Portal) and Phase 1 (Yoho Bridge) sections. The project will upgrade approximately 2.9 miles of highway through the most challenging section of the canyon to improve safety. Part of the project scope is to mitigate rock fall and avalanche hazards with bridges, rock catchment ditches and other measures. Further, wildlife exclusion fencing and wildlife passage opportunities were added to reduce vehicle-animal collisions.
Geology
Limestone, slate, dolomite.
Location
British Columbia, Canada
