China National Highway 213 (G213) runs from Ceke, Inner Mongolia, to Mohan, on the border with Laos, in Yunnan. It is in length and runs via Chengdu, Sichuan and Kunming, Yunnan. Before the 2013 Highway Planning, the route started in Lanzhou, Gansu. This route was a key transportation route into the disaster zone during the 2008 Wenchuan earthquake, and was referred to as a "lifeline" by rescue workers. On 6 July 2011, it was damaged by mudslides and collapses, including a stretch which was damaged as a result of the nearby river being diverted by a mudslide. For the extension to Ceke, a tunnel is being constructed on the pass on the Gansu-Qinghai border near Sunan County.
