Dalian build­ing un­der­wa­ter traf­fic tun­nel

China Daily (Canada) - - CHINA - By ZHU CHENG­PEI and ZHANG XIAOMIN

Dalian has started con­struc­tion of an un­der­sea tun­nel to ease in­creas­ing traf­fic jams.

Lo­cated at the south­ern tip of the Liaodong Penin­sula, the coastal city has only two main high­ways con­nect­ing its down­town area with its eco­nomic de­vel­op­ment area and ac­cess­ing other cities in North­east China.

The 5.4-km-long tun­nel, across Suoyu Bay, will pro­vide a third trans­porta­tion artery.

Yang Li­jun, an of­fi­cial with the city’s con­struc­tion depart­ment, said the dual three-lane car­riage­way is due to be com­pleted in 2019.

“It will not only re­lieve traf­fic con­ges­tion but also pro­mote the de­vel­op­ment of the nearby East Har­bor Commercial Area, the Suoyu Bay Commercial Area, and Xian­glu­jiao Lo­gis­tics Park,” he said.

The tun­nel and fa­cil­i­ties will in­volve an in­vest­ment of around 7.2 bil­lion yuan ($1.19 bil­lion).

Yang said the un­der­sea sec­tion of the tun­nel will be 2.7 km long and will use the same “im­merse cube method” en­gi­neer­ing tech­nol­ogy, as the Hong Kong-Zhuhai-Ma­cao Bridge did.

e method sees the pro­duc­tion of all com­po­nents on shore be­fore as­sem­bling and in­stalling them into the pre-built foun­da­tion trench on the seabed.

“Com­pared with drill­ex­plo­sion method, it is a more ad­vanced tech­nol­ogy. More im­por­tantly, it has been suc­cess­fully ap­plied in the con­struc­tion of the bridge, and that gives us con­fi­dence,” Yang said.

He said prepa­ra­tion work will be com­pleted this year.

The tun­nel re­quires 15 com­po­nents, each 180 me­ters long and 35 me­ters wide.

When the tun­nel is put into oper­a­tion, it will take only 10 min­utes to drive through.

“That would be great,” com­muter Li Xian­feng said. “You know, the ex­ist­ing 18-km-long road along the sea­side takes about 40 min­utes or even more to drive in rush hours.”

How­ever, other res­i­dents writ­ing on the Sina Weibo, a Twit­ter-like plat­form, have ex­pressed con­cerns.

“When Donglian Road (the sec­ond ma­jor artery in and out of down­town Dalian) opened in 2009, ex­perts said traf­fic jams would be greatly re­duced. Only a few years later, we need a new op­tion. The new projects can­not catch up with the in­creas­ing num­ber of new ve­hi­cles,” a user named Pin­mingdl com­plained.

Sta­tis­tics show there were more than 1.2 mil­lion ve­hi­cles in Dalian at the end of 2013, al­most triple the num­ber in 2008.

Sun Ming­nan, a lo­cal leg­is­la­tor, sug­gested op­ti­miz­ing pub­lic trans­porta­tion net­works to get more res­i­dents to take buses in­stead of pri­vate cars.

“People will choose the bus if it is more con­ve­nient and com­fort­able,” he said.

At present, Dalian has 23 des­ig­nated bus lanes dur­ing rush hours, and more pub­lic trans­port im­prove­ments are ex­pected in the coastal city. Con­tact the writer at zhangx­i­aomin@chi­nadaily. com.cn
