China has revived plans to build the world’s longest undersea tunnel, Reuters has reported.

According to the report, China plans to spend US$42 billion on the 123km tunnel to link the country’s eastern and north-eastern region.

The tunnel will be built across the Bohai Strait and will run from the port city of Dalian in the north-eastern Liaoning province to Yantai city in eastern Shandong. It is expected to cut the travelling distance between the two cities by 998km.

China initially announced plans to build the tunnel in 1994, at a cost of $10 billion, but no progress has been made since.

Currently, Japan’s 54-km Seikan tunnel is the world's longest undersea tunnel, while the Channel tunnel between England and France is 50.5 km long.
