These days, the construction atmosphere at the Ring Road 2.5 construction project, Dam Hong - National Highway 1A (Hanoi) is extremely urgent.
Many machines and workers are mobilized on the construction site, constructing "3 shifts, 4 crews" to ensure the set schedule.
The Ring Road 2.5 construction project, Dam Hong - National Highway 1A section, is invested in the form of a BT contract (build - transfer) with a length of 1.6 km, with a total investment of more than 1,300 billion VND.
The project started in 2014, expected to be completed in 2017 but was delayed.
By 2020, the project was temporarily suspended when it only reached about 40% of the workload. The reason is due to problems in site clearance and extension of BT contract appendices.
After 5 years of suspension, by the end of May 2025, with the permission of the Hanoi People's Committee, Hoang Mai - Hanoi Construction Investment Co., Ltd. (the project enterprise) organized the groundbreaking ceremony for the Ring Road 2.5 construction project, Dam Hong - National Highway 1A section.
Talking to a reporter from Lao Dong Newspaper, a representative of Hoang Mai Construction Investment Co., Ltd. - Hanoi said that up to now, the project construction progress has reached about 90%.
It is expected that on January 31, 2026, the Ring Road 2.5 project, Dam Hong - National Highway 1A section, will be technically opened to traffic after many years of people's expectations.
Along with Ring Road 2.5, the Kim Dong - Giai Phong intersection underpass project is also constructing the final items.
Mr. Tran Binh Dinh - Engineer of the underpass project management board said that the project has completed 90% of the workload to date. Technical opening is expected on February 10.
The Kim Dong - Giai Phong intersection underpass construction project has a tunnel length and access road of 890 m in the direction of Ring Road 2.5.
The project was started in October 2022, with a total investment of about 778 billion VND, invested by the Hanoi Traffic Construction Investment Project Management Board.
This is the 5th underpass project in Hanoi since 2009 after the Kim Lien, Trung Hoa, Thanh Xuan and Le Van Luong tunnels.
The Ring Road 2.5 construction project, Dam Hong - National Highway 1A section and Kim Dong - Giai Phong intersection underpass, when completed, will play an important role in improving traffic infrastructure, reducing congestion and connecting urban areas.
These are key transport projects creating motivation for socio-economic development for the southern part of the city.
