China to build world’s long­est un­der­wa­ter tun­nel

China Daily (Canada) - - NEWSCAPSULE -

The es­ti­mated cost is $36 bil­lion, and the length is 123 km (76 miles).

Those are the num­bers for what would be the world’s long­est un­der­wa­ter tun­nel that China plans to build be­neath the Bo­hai Sea by 2026. The plan is 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. Work on a fea­si­bil­ity re­port could take two or three years, he said.

The tun­nel will house a rail line con­nect­ing the port cities of Dalian in Liaon­ing prov­ince and Yan­tai in Shan­dong prov­ince. It will sur­pass the com­bined length of the world’s two long­est un­der­wa­ter tun­nels — Ja­pan’s Seikan Tun­nel and the Chan­nel Tun­nel be­tween Bri­tain and France.
