Plan drafted for $36b undersea tunnel

Record-setting project beneath Bohai Sea could be completed by 2026

China plans to build the world's longest underwater tunnel beneath the Bohai Sea by 2026, with a blueprint expected to be submitted to the State Council in April.

"Once approved, work could begin as early as 2015 or 2016," Wang Mengshu, a tunnel and railway expert at the Chinese Academy of Engineering who has worked on the plan since 2012, told China Daily.
