Route 90 is the longest Israeli road, at about 480 kilometres (300 mi), 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, though while it passes near the city of Jericho, it does not enter areas controlled by the Palestinian Authority. There are two checkpoints which separate this central section of the road from the northern and southern sections that are located inside the Green Line.
The section of route 90 passing through the Jordan Valley was dedicated as Derekh Gandi (Gandhi's Road) after the late Rehavam Zeevi, an assassinated Israeli Minister of Tourism, who was nicknamed after Mahatma Gandhi.
The section of Route 90 passing the Dead Sea is named Dead Sea Highway, and it is this location that is the lowest road in the world. It is along this stretch of road that Masada, Ein Gedi nature reserve, Ein Gedi Spa, Qumran Caves, and Ahava (company) are located.
The section of Route 90 passing through the Arabah is named Arava Highway.
