China revives plans to build world's longest sea tunnel

NSFW    China plans to invest 260 billion yuan, or roughly $42 billion, to revive plans to build the world's longest undersea tunnel, according to Reuters.

The plan, originally proposed in 1994, would link China's eastern and northeastern regions.

The 123-km tunnel running between Dalian in Liaoning province and Yantai in Shandong, would shorten the trip between the two cities from one day to just one hour.

Building undersea tunnels typically requires lengthy exploration work as tunnels must run through soil and rock layers of varying hardness.

The areas proximity to two earthquake fault zones presents another challenge. The region saw a 7.4 magnitude earthquake occur in the Bohai Sea in 1969 and a 7.3 magnitude earthquake hit Haicheng in southern Liaoning in 1975.

The state media announcement did not say when the project would be completed.
