Zhenba (Sichuan -Shaanxi) to the construction of the Sichuan -Shaanxi border project of Guang'an Highway to start construction

On September 26, 2022, the construction of key control projects such as Yongan Tongjiang Special Bridge and Yong'an Tunnel marked the official construction of the S15 Line Town Bazi (Sichuan -Shaanxi) from the Sichuan -Shaanxi border to the Wangping section of the Guang'an Expressway.

Zhenba (Sichuan -Shaanxi) to Guang'an Expressway Sichuan -Shaanxi Realm to Wangping section project "Sichuan Provincial Expressway Network Layout Plan (2022-2035)" in 13 vertical lines of the town of Pakistan to Chongqing to Chongqing, It is an important channel for strengthening intercontinental connections. The main line of the project starts from near the border of Sichuan -Shaanxi Province, Tiexi Town, Tongjiang County, Bazhong City. It is connected to the Shaanxi section of Shaanxi. Baishi Temple Village, Shaxi Town, connects Zhenba (Sichuan -Shaanxi) to the starting point of Wangping to Tongjiang section from the Guang'an Expressway, and simultaneously build the two river estuary branches. The route is 61 kilometers in length, and the two -way four -lane highway standard construction is adopted. The main line design speed is 100 kilometers per hour.

The project was jointly invested in the construction period by Shu Dao Group Shu Gao Company (leading party), Sichuan Highway Bridge Construction Group, Chengdu Construction Industry Group, and Sichuan Highway Planning and Design Research Institute for 4 years. It is planned to be opened to traffic in 2026. The construction of the project is of great significance for improving the north -headed Sichuan channel capacity, improving the road network structure in northeast Sichuan, and serving the revitalization and development of the Sichuan -Shaanxi Revolutionary District.

The project is located in the mountains of the mountains, with complex terrain and poor geological conditions. Poor geology such as empty areas, collapse, and rock piles prominent. The terrain along the route is steep, and there are fewer platforms. It is affected by the terrain, the net distance of the tunnel, and the special structural bridge. The ecological environment is sensitive, the environmental water protection requirements are high, and the bridge -tunnel ratio is as high as 87%, and the construction environment is extremely difficult. During the design stage, the project adheres to the concept of "resource conservation, ecological environmental protection, energy conservation and efficiency, and quality design". During the construction stage, the construction concept of "high -quality high -speed, safe high -speed, red high -speed, high -speed high -speed" construction concept will always be pursued, and the management concept of "service+control" will help the project high -quality construction.
