Beginning about 25 miles/40 km east of Dawson City, Yukon, the Dempster Highway is a four-season, 456 mile long gravel road that connects the Klondike Highway (Yukon Highway 5) to Inuvik in the Northwest Territories.
Services and facilities are few and far between and motorists are advised to carry a full-sized spare tire (or two spare tires if they are an unusual size) as well as extra water and gas.
Construction of the Dempster Highway began in 1959 and was finally completed in 1978. It was named for Inspector William John Duncan Dempster of the RCMP.
