1. Where is the Sichuan Tibet Highway?
Sichuan Tibet Highway, also known as the Chengdu-Lhasa Highway, is the most precipitous road in China running from Chengdu to Lhasa. It is a world-class scenic road travelling through Kham Tibetan areas and part of the Hengduan Mountainous Regions.
Specifically, the highway from Sichuan to Tibet comprises two parts: the southern route and the northern route.
The Southern Route is the west section and highlights of the G318 National Highway from Shanghai to Zhangmu on the China-Nepal border. Covering around 2146 kilometers, the southern route of the Sichuan Tibet Highway runs through Litang and Batang, and then enters the Tibet Autonomous Region in Markam, to further extend to Bomi and Nyingchi, before arriving in Lhasa.
The northern route, being part of the G317 National Highway, extends a little longer than the southern one, about 2412 kilometers. Starting from Chengdu, it runs through Garze, Dege, and towards Qamdo in Tibet, before arriving in Lhasa.
The two routes of the Sichuan Tibet Highway converge in Bamda, Qamdo. In most cases, the southern route via the G318 Highway will be the dominating road to take an overland trip from Lhasa to Chengdu, because of its breathtaking scenery and favorable road conditions.
