The Friendship Highway (also known as the China-Nepal Highway, Chinese: 中尼公路; pinyin: Zhongni Gonglu) is an 800-kilometre (500 mi) scenic route connecting the capital of Tibet, Lhasa, with the Chinese/Nepalese border at the Sino-Nepal Friendship Bridge between Zhangmu and Kodari. It includes the westernmost part of China National Highway 318 (Shanghai-Zhangmu) and crosses three passes over 5,000 m (16,400 ft) before dropping to 1,750 m (5,700 ft) at the border.

The 2015 earthquakes in the region closed the highway and caused many evacuations. By 2016 there were some repairs but trading on the route was not restored to pre-quake levels.
