Map of the “Pan-American highway.”

The Alaska Highway is the northern part of the unofficial Pan-American Highway, a drivable series of roads that begin at the top of Alaska and end at the southern tip of South America. The distance is nearly 30,000 continuous miles of roads, although there is a small break in the Colombian rainforest. Needless to say, it dwarfs most cross-country road trips.
