Explore Yukon Highways
This map is from a 1972 brochure, "travelling yukon", published by the Yukon Dep't of Travel and Information. The information on the highways reads:
The Canol Road
Highway 8, the Canol (Canadian Oil) Pipeline Road was another wartime construction job, built to service an oil pipeline from Norman Wells in the N.W.T. It branches north at Mile 836 of the Alaska Highway, joining the Campbell Highway at Mile 230 and continuing for another 129 miles to the Northwest Territories border. It's a summer road only and there are no services or facilities beyond Ross River.
See the Robert Campbell Highway page for that information from this brochure.
