The Department of Transport has just submitted to the Hanoi People's Committee a report proposing the investment policy to build an underpass connecting Hoang Quoc Viet Street with Pham Van Dong Street (Ring Road 3) and connecting with Tran Vy Street. The project is located in Cau Giay District and Bac Tu Liem District.

According to the report, the independent component project 2 - investing in the construction of an underpass on Hoang Quoc Viet Street, extending it with Pham Van Dong Street and connecting it with Tran Vy Street, has a total length of about 600m.

Specifically, the length of the closed tunnel is 275m, the length of the open tunnel is about 212m. The tunnel cross-section is 22.1m, arranged with 6 lanes, each side has 2 lanes for motor vehicles 3.5m wide and 1 lane for non-motor vehicles 2.5m wide.

The road on both sides in front of the Ministry of Public Security gate is 14.75m wide, including 4 lanes for motor vehicles, and the sidewalk is 4.5m wide.

The extended Hoang Quoc Viet Street has a cross-section of 50m. The current Hoang Quoc Viet Street has its sidewalks trimmed, the median strip adjusted, the right and left lanes widened, and the road around the intersection; technical infrastructure, trees, traffic lights, paint and overall traffic organization are built to ensure safety and urban beauty.

The project research scope is calculated from the center of the intersection towards Hoang Quoc Viet Street about 525m (intersection of Pham Tuan Tai Street), towards Tran Vy Street about 720m (intersection of Tran Vy Street).

The total project investment is expected to be more than 1,424 billion VND from the city budget, implemented from 2025 - 2028.

Explaining the urgency of investing in the project, the Department of Transport said that traffic volume on Hoang Quoc Viet and Ring Road 3 has been increasing continuously in recent years, and traffic organization with level intersections and traffic lights cannot meet the demand.

Therefore, there must be a solution to open more traffic directions, synchronizing the ability to relieve traffic pressure of the Hoang Quoc Viet - Ring Road 3 intersection with adjacent intersections.

Upon completion, the underpass at the intersection of Hoang Quoc Viet extended road and Pham Van Dong road will resolve traffic conflicts, reduce congestion at the intersection and adjacent intersections, and reduce costs and waiting time due to congestion.
