Su-Tong Yangtze River Bridge is centrally located in NETDA, some 100 km from the estuary of the Yangtze River, aimed to connect Nanjing -Nantong and Yancheng -Nantong Expressways to the north, and Shanghai -Nanjiang and Suzhou -Jiaxing -Hangzhou Expressways and Riverside Expressway in the south. It is a key transport link of Tongjiang -Sanya Coastal Expressway.
The Su -Tong Bridge spans 7,600 meters across the River. The main navigation channel is a two-tower stayed-cable bridge with main span of 1,088 meters and clearance of 62 meters. Container vessels of the fourth and fifth generations can go through smoothly at all weather conditions. With links to its north and south totaling 32 kilometers long, the completed bridge will be the largest among stayed-cable bridges in the world. Currently, the foundation of engineering and construction is duly completed, and the full-scale construction of Bridge tower bodies is under way. The bridge is expected to open to traffic in 2007.
