The Pan-American Highway (see below for its name in all languages) is a network of roads nearly 48,000 kilometres (29,800 miles) in total length. Except for the about 100 kilometer (62 mi) Darién Gap between Panama and Colombia (which is also considered very dangerous to cross on-land), the road links the mainland nations of the Americas in a connected highway system. According to The Guinness Book of World Records, the Pan-American Highway is the world's longest "motorable road".
The Pan-American Highway travels through the following 15 countries:
- Canada (unofficially)
- United States (unofficially)
- El Salvador
- Costa Rica
- Peru, where it goes through Lima
