Beginning at Chengdu, the Sichuan-Tibet Highway extends to the south and north at Xinduqiao via Wan and Kangding and joins together again at Bamda after entering Tibet. This highway has a high elevation and winds its way around mountains. During the rainy season it is blocked up owing to the landslide.
