Outline of the Project | The Nhat Tan Bridge is to be built to mitigate the ever-increasing traffic congestion in Hanoi City and vitalize the economy in Hanoi Metropolitan Area. The highlight of the project is the construction of a 300-m spans 6-span continuous cable-stayed bridge having a total of 1,500 meters long over the Red River. Such multi-span cable-stayed bridge has been used for the Millau Bridge in France and Rion Antirion Bridge in Greece, however, it is yet a new structural form in Asia. The bridge is characterized by its multi-spans in the cable-stayed bridge. It will adopt steel-concrete composite girders, high-strength stay cables, and high-strength concrete. It is also significant to the construction in the Red River which annual water level varies 10 meters. |  | 5-tower cable-stayed bridge side view | | | The project measures a total of 8.5km with 3.9-km bridge section, beginning from Phu Thuong Interchange, going north to cross the Red River and connecting the Vinh Ngoc Interchange where it meets National Highway No. 5 and No. 3 at the end.
