The total length of Wuwei Highway is 318.5 kilometers, which is an important channel for opening the traffic barrier in the north and south. The Tianshan Shengli Tunnel is the "throat" project of the highway, with a total length of 22.1 kilometers. It is a typical high -cold and high -altitude highway tunnel in the highway under construction in China. The geology is complicated, the geological fracture zone is through, and the construction is difficult.

The construction team of the fifth standard section and the sixth standard section of the China Jiaotong Urban Wuwei project is responsible for the construction and exit of the tunnel import and exit. The tunnel is divided into three holes of the left, middle, and right at the same time. The middle hole is the service tunnel. The hard rock excavation machine is tapped from both ends of the entrance and export to open up the auxiliary working surface for the left and right dual -main holes to achieve "long tunnel shorts" and effectively save the construction period.

Since the official start of the Tianshan Shengli Tunnel, the builders have overcome difficulties such as high altitude, high cold, traffic occlusion, complex geological, and high environmental protection requirements, and comprehensively promote the construction of the project.

The Wuwei Highway runs through Tianshan. It is expected to be opened to traffic in 2025. At that time, the transportation bottleneck from the north and south of Tianshan will be fully connected. The driving time between Urumqi and Korla will be shortened from the current 7 hours to 3 hours.
