The Alaska Highway (also known as the Alaskan Highway, Alaska-Canadian Highway, or ALCAN Highway) was constructed during World War II and connects the contiguous U.S. to Alaska through Canada. It runs from Dawson Creek, British Columbia to Delta Junction, Alaska, via Whitehorse, Yukon. Completed in 1942, it was 2,237 km or 1,390 mi long, but is becoming shorter due to rerouting. (Wikipedia)
