The Alaska Highway (also known as the Alaskan Highway, Alaska-Canaian Highway, or ALCAN Highway) was constructed during World War II and connects the Continental U.S. to Alaska through Canada. It runs from Dawson Creek, British Columbia to Delta Junction, Alaska, via Whitehorse, Yukon. Completed in 1943, it is 2,237 kilometres or 1,390 miles long. The historic end of the highway is near milepost 1422, where it meets the Richardson Highway in Delta Junction, Alaska, about 160 km (100 mi) southeast of Fairbanks. Mileposts on the Richardson Highway are numbered from Valdez, Alaska. The Alaska Highway is popularly (but unofficially) considered part of the Pan-American Highway, which extends south to Argentina.
