London, Feb 15: Chinese engineers have unveiled plans to build the world’s longest tunnel at a cost of about $37 billion.
At 77 miles (124 km), the Dalian-Yantai tunnel on the country’s eastern coast will save travellers an eight-hour ferry ride or 900-mile road trip.
The project could start within a couple of years, with completion scheduled for 2026, the Daily Mail reported, citing Chinese media.
Though the first proposal for the undersea link was made in 1994, it has been stuck in the planning stages ever since.
The tunnel will run from the port city of Dalian in northeastern Liaoning province to Yantai city in coastal province of Shandong. Engineers will submit a blueprint to the government by April for the tunnel and work could start as early as 2015 or 2016.
The world’s longest undersea tunnel, the Seikan in Japan, opened in 1988 after more than two decades of construction. The tunnel is 31 miles long.
