The Song Da Construction Corporation reports that 4,088m of tunnel at the south end of the Hai Van Pass will be finished by late October.

The work includes a 2,400m long by 13m wide main tunnel and a 2,400m long by 5.1m wide evacuation tunnel.

The entire project, a 12.18km complex that will link Lang Co in Thua Thien-Hue Province with Da Nang, is due for completion next year.

The 6.2km, two-lane main tunnel and its access roads to Highway 1 are designed to reduce the road distance over the Hai Van Pass by 9km, accommodating vehicles of up to 30 tonnes, travelling at 80km per hour.

The company says that since construction began two years ago, workers have unearthed 17,789 cu.m of soil, 278,144 cu.m of rock, and 480,000 cu.m of soil of the tunnel gate’s groundwork.

The corporation has poured 16,000 cu.m of concrete for the main tunnel. It was also asked by the Ministry of Transport to build 900m of the tunnel at the north end, including 450m of the main tunnel and 450m of the evacuation tunnel.

The work has been conducted under the close supervision of international and domestic experts from the Japanese Nippon Koei, American Louis Berger and Vietnamese Tedi companies. — VNS
