Add another artery to the southward Izukawa! At 24 o'clock on February 8, the two-way six-lane expressway with the highest bridge-tunnel ratio in the country--- Gujin Expressway, which was invested and constructed by Shudao Expressway Group and participated in the construction of Sichuan Road and Bridge, was completed and opened to traffic for trial operation, marking the opening of the most convenient high-speed channel from Chengdu to Guiyang on the occasion of the New Year of the Dragon. The journey from Luzhou to Guiyang will be shortened by about 50 kilometers, and the time will be shortened from 4 hours to 3 hours.
The total length of the Gujin Expressway is 38559 kilometers, starting from Gulin County, Luzhou City, connecting the Xuyong to Gulin Expressway that has been opened to traffic, ending at the Sichuan-Guizhou Provincial Boundary of Jiaoyuan Town, Gulin County, connecting Guiyang to Gulin (Sichuan-Guizhou Boundary) Expressway that has been opened to traffic through Jinsha (Sichuan-Guizhou boundary), the main line adopts two-way six-lane, the design speed is 100 kilometers per hour, and the overall roadbed width is 335 meters, the project bridge-tunnel ratio is as high as 805%。
A number of super projects have built a new "heavenly road" in Wumeng
The whole line of Gujin Expressway is located in the Wumeng Mountains on the edge of the Sichuan Basin, which is a typical mountain expressway, which has crossed deep valleys and rivers for many times, and there are many undesirable geologies such as slopes, karst, gas, and water inrushes, which are extremely difficult to construct, have high environmental protection requirements and high safety risk coefficients. Among them, the main control project Shuiluohe Bridge is the world's largest span suspension arch bridge, Chishuihe Bridge is the largest span of the same type of mountain bridge in Asia, the double-tower double-cable-surface composite beam cable-stayed bridge, and the girder sub-tunnel is the first large-section gas outburst tunnel in Sichuan Province. In order to promote the construction of the project with high standards, safety and environmental protection, the project builder pioneered the digital intelligent bridge construction, management and construction operation system, created a model of intelligent manufacturing, implemented the idea of green construction in the whole process, effectively guaranteed the ecological environment of the Chishui River Basin, piloted the construction of the first standardized industrial worker park in the province, and fully implemented the industrial chain and industrial coordination.
The Gujin Expressway is temporarily free of charge.
Xie Ke, director of the engineering management department of the Sichuan-Guizhou Company of Shudao Expressway Group, told reporters that after the project is completed and opened to traffic, it will unblock the southbound comprehensive transportation channel of Sichuan to Sichuan, strengthen the land passage capacity of Sichuan and Beibu Gulf ports and Guangdong-Hong Kong-Macao Greater Bay Area, improve the regional investment environment, promote the development of regional resources, promote the cross-regional flow of factors, drive the people to increase their income and get rich, and boost the rural revitalization of the areas along the line.
