According to the submission of the Department of Transport to the Hanoi People's Committee, the project to build an underpass on Hoang Quoc Viet road extended with Pham Van Dong street (Ring Road 3) and connected with Tran Vy street, with a total length of about 600m (of which the closed tunnel length is 275m, the open tunnel length is about 212m...).
The tunnel surface is 22.1m wide, with 6 lanes, 2 lanes for 3.5m wide motor vehicles on each side and 1 lane for 2.5m wide non-motor vehicles.
The roads on both sides in front of the Ministry of Public Security gate are 14.75m wide, including 4 lanes for motor vehicles, with sidewalks 4.5m wide. Hoang Quoc Viet extended road has a cross-section of 50m.
Hoang Quoc Viet Street is currently covered with sidewalks, the median strip is adjusted, the right and left lanes are expanded, the road around the intersection is expanded; construction of technical infrastructure, trees, traffic lights, painting and organizing overall traffic to ensure safety and urban aesthetics.
The scope of the project is calculated from the intersection towards Hoang Quoc Viet Street about 525m (the intersection of Pham Tuan Tai Street), towards Tran Vy Street about 720m (intersection of Tran Vy Street).
The total estimated investment of the project is more than 1,424 billion VND from the city budget. The implementation period is 2025 - 2028.
In addition, 2 sub-projects for compensation, resettlement support, and relocation of technical infrastructure are implemented by the People's Committees of Cau Giay District and Bac Tu Liem District.
A representative of the Hanoi Department of Transport said that in recent years, the traffic volume on Hoang Quoc Viet and Ring Road 3 has been increasing continuously. Traffic organization with level intersections and traffic lights cannot meet the demand, so there must be solutions to open more traffic routes, synchronizing the ability to relieve traffic pressure of the Hoang Quoc Viet - Ring Road 3 intersection with neighboring intersections.
The investment in the construction of Hoang Quoc Viet underpass extended to Pham Van Dong Street and connecting to Tran Vy Street is in line with the orientation of the General Planning for Construction of the Capital, the Traffic Planning of Hanoi Capital to 2030, vision to 2050 and the Urban Zoning Plan H2-1...
After completion, the underpass at the intersection of Hoang Quoc Viet Street and Pham Van Dong Street will resolve traffic conflicts, reduce traffic congestion at intersections and adjacent intersections, reduce costs and waiting time due to traffic congestion, reduce environmental pollution in urban areas, and gradually complete the traffic infrastructure system according to the approved plan.
