Lhasa
Road

The Qinghai–Tibet Highway (part of G109) runs northeast toward Xining and eventually to Beijing and is the most-used road in Tibet. The Sichuan–Tibet Highway (part of G318) runs east towards Chengdu and eventually to Shanghai. G318 also runs west to Zhangmu on the Nepal border. The Xinjiang-Tibet Highway (G219) runs north from Lhasa to Yecheng, and then to Xinjiang. This road is rarely used due to the lack of amenities and petrol stations. A new 37.68 kilometres (23.41 mi), four-lane highway between Lhasa and the Gonggar Airport was built by the Transportation Department of Tibet at a cost of RMB 1.5 billion. This road is part of National Highway 318 and starts from the Lhasa railway station, passes through Caina Township in Qushui County, terminating between the north entrance of the Gala Mountain Tunnel and the south bridgehead of the Lhasa River Bridge, and en route goes over the first overpass of Lhasa at Liuwu Overpass.
