The Yibin Lingang Yangtze River Bridge spans the Yangtze River in Lingang District of Yibin City. It is a control node project for the national eight vertical and eight horizontal key projects of Rongkun High-speed Railway, Chongqing-Kunming High-speed Railway and the newly built Sichuan-South Sichuan Intercity Railway. River channel. In order to save channel resources and project investment, a four-lane railway and six-lane highway road-rail dual-use bridge scheme is adopted. The bridge has a main span of 522m, a total length of 1742.1m, a width of 63.9m, and a total investment of 2.54 billion yuan. After completion, it will become the world’s widest road-rail dual-use bridge, the world’s largest road-rail dual-use steel box girder cable-stayed bridge, and the first domestic road-rail flat-layer cable-stayed bridge. The bridge adopts 7.0mm-1860Mpa-class parallel steel wire stay cables. The cables are arranged in a fan-shaped double-cable plane. The double-row cables are arranged in a single group of cable planes across the bridge. It has the characteristics of novel structure, high technical content, and difficult control.
