In the upcoming transportation infrastructure development plan, Hanoi is considering investing in an underground tunnel crossing the Red River in the southern area.
With an estimated total investment of approximately 24,604 billion VND, the project is expected to become a strategic connection axis, opening up new development space for both sides of the river by 2026.
The tunnel route will have a total length of about 6 km, including a 3.65 km main tunnel section passing under the riverbed. The structure consists of two parallel tunnel tubes, each with a diameter of 15.2 meters. With a cross-section width of 40 meters across the entire route, this is considered one of the most technically and constructively complex underground transportation projects ever undertaken in the capital.
Regarding connectivity, the southern road tunnel will start at the intersection of Linh Nam and Nguyen Khoai streets in Linh Nam ward. This prime location within the southern transportation network directly links riverside roads with vital ring roads. After crossing the Red River, the tunnel will end at the intersection of Ly Thanh Tong and Giap Hai streets in Bat Trang commune. This route not only alleviates pressure on Vinh Tuy and Thanh Tri bridges but also stimulates robust development in the eastern core area of the city.
Land clearance for the project is advantageous, as the section passing through Bat Trang commune primarily consists of agricultural land. While the connection area on Ly Thanh Tong street does pass through a residential zone, the impact is considered minimal, facilitating timely project implementation by 2026.
Upon completion, the project will not only address immediate traffic congestion issues but also realize the Red River flood diversion plan, contributing to a modern and sustainably developing capital city. With a record investment of over 24,600 billion VND, the southern Red River road tunnel will undoubtedly be a key infrastructure project, reshaping Hanoi’s urban transportation landscape in the coming decade.
