Hanoi will conduct further studies on a project to build an underwater tunnel across the Red River, local news website VnExpress reported Saturday.
Phi Thai Binh, vice chairman of Hanoi People's Committee said at a meeting Friday that it was necessary to build another traffic line to connect the river's banks, but related agencies need to present more convincing reasons for building a tunnel as well as estimates about investors' capacities.
The meeting was held by the city authorities to discuss the project proposed by the VinGroup Corporation and the Truong An Company, which is under the Ministry of National Defense, the website reported.
Most representatives from agencies like the Department of Planning and Investment, and the Department of Transport agreed with the proposed project to build a four-lane tunnel that is 1.5km long and 18-10m wide.
La Thi Kim Ngan, chief of the Hanoi Urban Planning Institute, said an underwater tunnel will cost less than a normal bridge that needs site clearance money at either end. The tunnel will not affect the river's capacity to regulate floods, she said.
The project will be submitted to the city Party Committee before being presented to Prime Minister for approval.
Last September Vietnam completed its first underwater tunnel across the Saigon River in Ho Chi Minh City. The 1.5-kilometer long tunnel, the largest of its kind in Southeast Asia, is expected to open to traffic this November.
