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 scope of work includes:
- Upgrading approximately 4.8 kilometres of highway through the most challenging section of the canyon to improve safety
- Realigning 13 curves and widening the highway to four lanes with median barriers and wider shoulders to accommodate cyclists
- Mitigating rock fall and avalanche hazards with bridges, rock catchment ditches and other measures
- The construction of numerous retaining walls, and the installation of wildlife exclusion fencing and passages
The Phase 4 “Canyon” section is the last and most difficult part of the entire Kicking Horse Canyon Project. The improvements must be built with a view to safety, cost-effectiveness and as little disruption as possible to highway users and the community. Three phases of work have already been completed, resulting in more than 21 kilometres of roadway upgraded to a modern four-lane, 100 km/h standard. Overall, the project will improve safety and mobility over approximately 26 kilometres of a narrow, winding two-lane highway.
