The Alaska Highway was constructed during World War II to connect the contiguous United States to Alaska across Canada. It begins at the junction with several Canadian highways in Dawson Creek, British Columbia, and runs to Delta Junction, Alaska, via Whitehorse, Yukon. When it was completed in 1942, it was about 2,700 kilometres (1,700 mi) long, but in 2012, it was only 2,232 km (1,387 mi). This is due to the realignments of the highway over the years, which has rerouted and straightened many sections. The highway opened to the public in 1948. Once legendary for being a rough, challenging drive, the highway is now paved over its entire length. Its component highways are British Columbia Highway 97, Yukon Highway 1, and Alaska Route 2.

Alaska is a non-contiguous U.S. state on the northwest extremity of North America. It borders the Canadian province of British Columbia and the Yukon territory to the east; it shares a western maritime border in the Bering Strait with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north and the Pacific Ocean lies to the south. Technically a semi-exclave of the U.S., it is the largest exclave in the world.
