Nhat Tan Bridge (Hanoi Ring Road No. 2)

caunhattan-6e0b1

The Nhat Tan Bridge, which is located approximately 3.5km downstream of Thang Long Bridge, is planned to mitigate further congestion in the already congested bridges over the Red River. The main bridge is designed as six-span continuous cable-stayed bridge which forms the signature span of the project. Among three interchanges constructed in the Project, Vinh Ngoc Interchange will connect Nhat Tan Road and National Highway No.5. The northern end of the project road will be extended to Noi Bai Airport.
