Nguyen TanDong, Vice Chairman of Deo Ca Joint Stock Company – the unit constructing thetunnel – said the project marked an important milestone in the nationaltransport sector because it was the longest road tunnel in Southeast Asia, withconstruction completed by Vietnamese workers.
“We aremobilising many teams to do three shifts all day and night to bring the projectto completion as scheduled by the end of 2020,” Dong said.
Constructionof the approaching road, linking Lang Co town in Thua Thien-Hue province to thetunnel, was 95 percent finished, he said.
For HaiVan Bridge, the contractor has already completed 23 of 26 girder bridges sofar, the online newspaper Zing reported.
Dong saidcompared to the plan, the construction was more than two months ahead ofschedule, so it was feasible that the tunnel would be put into operation by theend of 2020.
While theHai Van Road Tunnel 2 was officially put into operation, it was expected tohelp in reducing traffic pressure for the current Hai Van Road Tunnel 1. Itwould shorten travelling time for vehicles and improve the efficiency oftransporting goods and passengers, he said.
