The Tianshan Shengli Tunnel built by CCCC is 2,800 meters above sea level. It is the "throat" project of Wuwei Expressway and the longest expressway tunnel under construction in the world.

The total length of the tunnel is 22.1 kilometers, which is close to the sum of the five Nanjing Yangtze River Bridges.

Tianshan stretches for about 1,760 kilometers in China, with an average width of 300 kilometers. It divides Xinjiang into southern and northern Xinjiang like a thick book spine. For the construction of the core area of the Xinjiang Silk Road Economic Belt, opening up the "barrier" of transportation will change. be particularly important.

In the past ten years, highway projects across the Tianshan Mountains have been implemented one after another, and they have continued to break through the limits. The builders have built the Baja Highway on the east line along the Tianshan Mountains, the Wuwei Expressway on the middle line is under construction, and the Duku Expressway on the west line is also under construction. In the preparations for the fierce battle, they will all pass through the Tianshan Mountains and become the road of happiness through the northern and southern Xinjiang.Editor/Ma Xue
