Kicking Horse Canyon Project – Phase 4 – Project Overview

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 4.8 kilometres of highway through the most challenging section of the canyon to improve safety
  • Realign 13 curves and widen the highway to four lanes with median barrier and wider shoulders to accommodate cyclists 
  • Mitigate rock fall and avalanche hazards with bridges, rock catchment ditches and other measures
  • Add wildlife exclusion fencing and wildlife passage opportunities to reduce vehicle-animal collisions 

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. A concept plan has been developed as a “reference design” to accompany the written specifications in the design build contract. The contractor will be responsible for preparing a design that meets or exceeds the minimum requirements contained in the reference design.

The total project cost for Phase 4 is estimated at $601 million. The project is cost-shared, with the Government of Canada contributing $215 million.
