China Plans World's Longest Underwater Tunnel
The tunnel will run from the port city of Dalian in northeastern Liaoning province to Yantai city in eastern Shandong. Today the drive between Dalian and Yantai takes around seven to eight hours. The Bohai Tunnel would shorten that to an hour.
China announced plans in 1994 to build the tunnel, at a cost of US$ 10 billion, and set to be completed before 2010. But more than 20 years on, the project remains stuck in the planning stage without elaborating.
Currently world's longest undersea tunnel is in Japan. The 54 kilometer Seikan tunnel links Honshu and Hokkaido islands and started operating in 1988 after more than two decades of construction. The Channel tunnel between England and France is about 51 kilometer long.
