Alaska Highway, road (1,387 miles [2,232 km] long) through British Columbia, Yukon, and Alaska. It was previously called the Alaskan International Highway, the Alaska Military Highway, and the Alcan (Alaska-Canadian) Highway. Connecting Dawson Creek, British Columbia, with Fairbanks, Alaska, the road was constructed by U.S. Army engineers (March–November 1942) at a cost of $135 million as an emergency war measure to provide an overland military supply route to Alaska. The Canadian part (1,200 miles [1,930 km], mostly gravel) was turned over to Canada in 1946. A scenic route open all year round, it joins highways to Edmonton and Prince George (in the south) and highways to Valdez, Anchorage, Seward, and Haines (in the north). The modern route is shorter than the original highway due to the rerouting and straightening of the road in some places.
