This paper describes the planning procedures used to develop a system of passing lanes for roads in the Canadian Rocky Mountain National Parks. The roads, which serve a wide range of trip purposes including international, interprovincial, and recreational traffic, are located within six mountain parks and include the Trans-Canada Highway, the Icefields Parkway, and the Kootenay Parkway. The road network in the Mountain National Parks consists of high standard design two-lane highways built in the 1950's and 1960's. Some of the roads, notably the Trans-Canada Highway in Banff National Park are currently carrying traffic volumes and a vehicle mix, including slow moving vehicles such as recreational vehicles, beyond their original design capacity.
