Construction to begin in 2018 and take three years to complete.

Authorities in central Da Nang city have finalised plans for the construction of a tunnel under the Han River, a symbol of the city.

The city’s Party leadership and its People’s Committee decided on an option for the tunnel at the last technical meeting on December 27, after four sessions over the course of more than a year, despite there still being some controversy over the project.

Le Van Trung, director of the Da Nang Department of Transport, told VET that the city’s leaders have agreed on the construction of a tunnel instead of a bridge, which would connect the two banks of the Han River from Dong Da Street to Tran Hung Dao Street.

“The project is expected to start in 2018 and be completed within three years,” Trung said. Local authorities approved the construction option proposed by the Bridge and Tunnel Engineering Consultants JSC (BRITEC) under the Ministry of Transport.

The tunnel will have a length of 1.315 km with investment capital estimated at more than $206 million and operating expenditures of around $1.2 million annually. Some 210 households on the two banks of the river will be relocated and compensated as part of site clearance.

BRITEC recently submitted three options for the tunnel to local authorities, including straight and dipping tunnels. City leaders chose the straight option to reduce the slope when entering the tunnel, which it considers to be safer, despite it involving more site clearance.

Hoang Phuong Hoa, Head of the Bridge – Tunnel Faculty at the Da Nang University of Science and a member of the judging panel in a contest for the design of the Han River tunnel, said the city did not choose the only design submitted as it did not meet criteria.

City leaders prefer a tunnel rather than a bridge so as not to impede traditional boat races and firework festivals. It will also be convenient during the wet season, according to Hoa.

Some experts have spoken out against the project, saying it isn’t necessary as transport needs from Hai Chau to Son Tra district are not significant and it would only serve about 150,000 households.

Meanwhile, Hoang Quang Huy, Chair of the Da Nang Urban Planning Association, believes a tunnel is appropriate because there are already six bridges across the Han River over a distance of 6 km. The city should therefore not build any more because bridges hinder the passage of boats.

He added that the only design submitted by a joint venture between a company under the Ministry of Transport and the Oriental Consultants Global Company Ltd of Japan has some shortcomings but, because it is the only option, Da Nang can allow the company to adjust the design to fit requirements.

“If Da Nang builds the Han River Tunnel, this will be the first river tunnel in central Vietnam and will become another tourist destination in the city,” Huy said, adding that the city has sent two working groups to HCM City to study the Thu Thiem Tunnel, which runs under the Saigon River and was Vietnam’s first river tunnel.
