Shanghai Chongming Cross-River Tunnel Yangtze River Bridge Project

Project Overview:

Shanghai Chongming Cross-river Tunnel is an important part of the national road construction plan for Shanghai to Xi'an determined by the Ministry of Communications. The project is 25.5 kilometers in full length. The project adopts the design of 'tunnel in the south and bridge in the north'. Its 8.9- kilometer tunnel crosses the Southport water area and its 10.3-kilometer bridge covers the Northport water area. The connection road between Changxing Island and Chongming Island is approximately 6.3 kilometers long. The main span of the bridge covers 730 meters, which was No.3 largest span in China and No. 5 in the world at the time of its completion. The project was started in 2004 and completed in 2009.
