Jinsha River 金沙江

Construction of the Xianglushan Tunnel, part of the Central Yunnan Water Diversion Project near the Jinsha River in Yunnan, has entered a critical phase. The tunnel is more than 63 kilometers long.

In Aba, Sichuan, construction of the Sichuan–Qinghai Railway is being stepped up. As a key part of the Lanzhou and Xining–Guangzhou corridor in China's “eight vertical and eight horizontal” high-speed rail network, the Sichuan–Qinghai Railway will connect the Songpan grasslands traversed by the Red Army during the Long March to the national network of railways served by multiple-unit trains, ending the remoteness of the northwestern Sichuan plateau. Deep in the mountains beside the Jinsha River in Yunnan, construction of the Xianglushan Tunnel, the longest tunnel in the Central Yunnan Water Diversion Project, has entered a critical phase. The tunnel is more than 63 kilometers long and extremely difficult to build.
