The Qujiang Grand Bridge on the Chengdu-Dazhou-Wanzhou High-Speed Railway — the world’s longest-span low-tower cable-stayed bridge for a double-track high-speed railway — was successfully joined on November 26.
The project, undertaken by China Railway 15th Bureau Group Corporation Limited, a subsidiary of China Railway Construction Corporation Limited (CRCC), marks a significant step toward full-line completion.
Located in Quxian County, Sichuan Province, the bridge is considered the “throat project” of the entire line. It spans a total length of 1,983.81 meters, including a 556.7-meter prestressed concrete low-tower cable-stayed main span. It features 36 cast-in-place segments, a 14.6-meter-wide deck, 50-meter-high towers, and 40 stay cables.
The bridge alignment required millimeter-level precision. Due to complex geological conditions along the route, construction was highly challenging. The project team overcame multiple technical hurdles to ensure the structure’s safety, durability, and high-quality delivery. (....)
