Parks Canada has constructed downgrade-passing lanes on the Trans Canada Highway in the Kicking Horse Pass in Yoho National Park and on Beaver Hill in Glacier National Park. These downgrade-passing lanes complement the passing lane system on the Trans Canada Highway in the Mountain National Parks. The purpose of this paper is to report on the experience of Parks Canada in designing, constructing and operating downgradepassing lanes. The paper also offers suggestions as to how climbing lanes and downgrade passing lanes could be combined on two-lane highways in mountainous terrain. For the covering abstract of this conference see ITRD number E211426.
