Projects
Chongqing High-tech Zone Yanshan Avenue Project

The total length of the project road is 25km. It is an urban trunk road dominated by freight traffic, with two-way eight-lane. The design speed is 60km/h. The construction and installation cost is about RMB 7.5 billion yuan. The project is located at the southern foot of Zhongliang Mountain, with complex topographic and geological conditions. The project crosses with 8 mountain-crossing arteries, 4 tracks, 4 railways and 5 reservoirs, so the project is very difficult.
