Chongqi Highway Railway Yangtze River Bridge spans the north branch of the Yangtze River estuary, and it is currently the fastest road-rail dual-purpose cable-stayed bridge on the Yangtze River in China. The main navigable hole bridge and the non-navigable hole steel girder adopt the steel truss plate combined beam structure, which is the world's first highway concrete bridge deck to participate in the first system of steel truss-plate combined beam cable-stayed bridge. The steel girder of the 17 piers of the main bridge adopts the jacking construction, and its length and weight are the largest among the domestic high-speed railway dual-purpose bridges.
