Chongming-Qidong Yangtze River Road-Rail Bridge is the controlling node project of Shanghai-Nanjing-Hefei High-speed Railway, with a total length of 4.09 kilometers, across the northern branch channel of the Yangtze River estuary. Its structure is a double-deck arrangement of dual-purpose bridge, the upper layer is a first-class highway with two-way 6-lane and maximum speed of 100 km/h speed; the lower layer is a double-lane high-speed railroad with the maximum speed of 350 km/h and a double-lane intercity railroad with the maximum speed of 250 km/h. The bridge is divided into the main navigable bridge, non-navigable bridge, combined rail and road approach bridge on the north and south shores, and single railroad approach bridge on the north and south shores; among them, the main navigable bridge is a double-tower double-cable plane cable-stayed bridge with steel truss composite beam, which is the world's largest span double-tower double-cable plane road-rail dual purpose ballastless track cable-stayed bridge.
