The Tarim Desert Highway crosses the Taklamakan desert from north to south. The total length of the highway is 552km; approximately 446km of the highway cross uninhabited areas covered by shifting sand dunes, making it the longest such highway in the world. To prevent the road from being buried by sand, China authorities have built a 60-meter-wide tree belt along the route provided with a massive irrigation system which pump water for the vegetation.
