China National Highway 216

China National Highway 216 is a highway in Xinjiang and Tibet, China. With the 2013 National Highway Network Plan, the route was extended north to Hongzhanzui in Fuhai County on the border with Mongolia, and extended south to the boundary with Nepal in Gyirong County. Originally it ran in the general southern direction from Altay City, Xinjiang to Baluntai, where it joins China National Highway 218. It was originally 857 kilometres in length. After landslides blocked Zhangmu port of entry, for a while, G216 was the only road link between Nepal and Tibet.
