The Pan-American Highway
The Pan-American Highway is a network of roads measuring about 48,000 km in total length except for a rainforest break of approximately 100 km, called the Darien Gap. The road links almost all of the mainland nations of the Americas in a connected highway system. According to Guinness World Records, the Pan-American Highway is the world’s longest “motorable road”. Because of the Darien Gap, it is not possible to cross between South America and Central America by road.
The Pan-American Highway passes through many diverse climates and ecological types from dense jungles to arid deserts, some of which are passable only during the dry season and in many regions driving is occasionally hazardous. The Northern Pan-American Highway travels through 9 countries and the Southern Pan-American Highway travels through 9 countries, it means Pan-American Highway travels through total 18 countries in America.
