Pan-American Highway
The Pan-American Highway is a network of roads stretching across the American continents and measuring about in total length. Except for a rainforest break of approximately , called the Darién Gap, the roads link almost all of the Pacific coastal countries of the Americas in a connected highway system. According to "Guinness World Records", the Pan-American Highway is the world's longest "motorable road". However, because of the Darién Gap, it is not possible to cross between South America and Central America with conventional highway vehicles. Without an all-terrain vehicle, it is necessary to circumnavigate this terrestrial stretch by sea.
Highway 90 (Israel/Palestine)
Route 90 is the longest Israeli road, at about , and stretches from Metula and the northern border with Lebanon, along the western side of the Sea of Galilee, through the Jordan River Valley, along the western bank of the Dead Sea (making it the world's lowest road), through the Arabah valley, and until Eilat and the southern border with Egypt on the Red Sea. The central section of the road traverses the West Bank; while it passes near the city of Jericho, it runs through Area C and does not enter areas controlled by the Palestinian Authority.
