Tianshan Shengli Tunnel

Tianshan Shengli Tunnel (Chinese: 天山胜利隧道, romanized: Tiānshān Shènglì Suìdào, lit. 'Tianshan Victory Tunnel') is a highway tunnel under construction in the Tianshan Mountains of Xinjiang, China.[1][2] It is designed as two parallel tubes, each with two lanes of traffic. When completed, the tunnel will be about 22.13 kilometres long and is expected to become the longest expressway tunnel in the world.[3]

The tunnel is part of the Ürümqi–Yuli Expressway, connecting Ürümqi in the north of Xinjiang to Yuli in the south.[4] Around 3,000 workers took part in the construction at elevations above 3,000 metres.[5] The travel time will decrease from about seven hours to just over three hours once the tunnel is functional.[6] The construction cost of the tunnel is estimated at ¥26.8 billion (around US$3.8 billion).[7]
