China finishes construction of tunnel link to Pakistan, plans new record breaking tunnel

Announces plans to build the world’s longest undersea tunnel measuring 123 km to link two major cities.

China has just completed the construction of one of its longest tunnels which will enable it to build a rail link with Pakistan.  The completed tunnel runs 22.24 km in the mountainous Xinjiang Uygur Autonomous Region and will reduce the distance between Turpan with Korla in southern Xinjiang by 122 km. Currently the distance between these two points on the Nanjiang Railway is 334 km.

It is said that the tunnel is part of China’s efforts to prepare the comparatively under developed Xinjiang province to take advantage of the planned China-Pakistan economic corridor.  Chinese leaders are also hoping that enhanced economic development will help to lessen the ongoing and bloody strife among a section of Uygur Muslims in Xinjiang.

China to construct the longest undersea tunnel starting in 2015


China plans the world’s longest tunnel, 123-kilometre from the northern city of Dalian to Yantai.

The 123-kilometre tunnel will be more than twice the length of the Channel Tunnel (50 kilometers) that connects the U.K. and France, China’s latest mega project is not short of ambition. It will run between the northern city of Dalian and Yantai, on the east coast. There will be three bores. One for high speed rail, one for cars and another for maintenance.

“Work could begin as early as 2015 or 2016,” The China Daily quoted Wang Mengshu, an expert at the Chinese academy of Engineering, as saying. The tunnel will also form a vital link in a high-speed rail line from the frozen parts of northern China to the tropical island of Hainan in the south.

Construction of the ambitious tunnel will require precise engineering skills of the kind that it took during the building of Tibet railway over frozen mountains, sources said. The tunnel passes through two earth quake fault lines. This includes Tangshan city, which was destroyed in 1976 after a 7.5 magnitude earthquake.
