Haitai Yangtze River Tunnel

Haitai Yangtze River Tunnel in east China's Jiangsu province is under construction. The tunnel is a key project to forge a major trans-river road link under China's longest river, connecting Haimen in the city of Nantong with Taicang in the city of Suzhou. 

Stretching approximately 39.07 kilometers in total, the tunnel includes an 11.185-kilometer underwater section, with 9,315 meters to be excavated using a TBM. It is designed as a six-lane, bidirectional highway with a speed limit of 100 km/h.
