Recently, the Fujiang Grand Bridge in Suining, a key control project on the Chengdu–Dazhou–Wanzhou High-Speed Railway, was successfully closed, marking the full structural connection of Southwest China’s largest-span steel–concrete hybrid girder cable-stayed bridge for high-speed rail.

Located in Chuanshan District, Suining, Sichuan Province, the Fujiang Grand Bridge is one of the most technically demanding control projects along the line. The bridge has a total length of 5,585.4 m, with its main bridge designed as a special H-shaped double-tower, double-cable-plane steel–concrete hybrid girder cable-stayed structure. Its 305-meter main span ranks first in Southwest China and second nationwide among bridges of the same type.

According to Li Shengping, Commander of the Suining Construction Headquarters of Chengdu–Dazhou–Wanzhou High Speed Railway Co., Ltd., the Fujiang Grand Bridge features a large span and a complex structural stress system. Its successful completion marks the beginning of the final critical phase of construction across the entire line. Currently, out of 136 tunnels, 130 have been completed, while 86% of bridge works and 96% of subgrade works are finished. The project has now entered the stages of ballastless track laying, station building, and “four-electrification” system installation (power supply, communication, signal, and information systems).

The Chengdu–Dazhou–Wanzhou High-Speed Railway extends 477 km with a design speed of 350 km/h, forming an important segment of the “Eight Vertical and Eight Horizontal” high-speed railway network’s Yangtze River corridor. The completion of this line will play a vital role in connecting Sichuan Province directly with the Yangtze River Delta and the Beijing–Tianjin–Hebei economic zones, while advancing the development of the Chengdu–Chongqing Twin-City Economic Circle through enhanced high-speed rail connectivity.
