Introduction of Tongling Yangtze River Railway Bridge?

Tongling Yangtze River Highway Railway Bridge is the key construction project of "86 1" plan in Anhui Province in 2008. It is the control project of Anhui section of Beijing-Fuzhou high-speed railway, and it is also the river-crossing passage of Hefei-Wuhu-Bengbu Railway and Tongling-Chaohu Expressway.

In terms of functional design, as a highway-railway bridge, Tongling-Wuwei-Chaohu Expressway is built, with six lanes in two directions, a road width of 33.5 meters and a design speed of 100 km. Four railway double tracks will be built below, in which the design speed of Beijing-Fuzhou High-speed Railway Passenger Dedicated Line is 350km/h, and the design speed of He Lu Copper-Railway Dedicated Line as the north-south freight passage is160km (the speed increase condition of 200km/h is reserved).

The construction of the bridge has been completed, which has refreshed the new history of the construction scale of Wanjiang Bridge.

Tongling Yangtze River Railway Bridge started construction on 20 10. The main bridge across the river is 1290 m long and adopts a cable-stayed bridge structure with two towers and five spans. The main span is 630 meters, which has set a new record for the span of highway and railway bridges in China. The bridge is divided into upper and lower floors, the lower floor is a four-lane railway and the upper floor is a six-lane expressway. After the completion of the bridge main body, carry out leak detection and vacancy filling operations to ensure the joint debugging and commissioning of Hefei-Fuzhou high-speed railway in early 20 15, and it will be completed and opened to traffic in July 20 15.
