Ha Noi begins construction of belt road No. 4
VGP - The Ha Noi People’s Committee held a groundbreaking ceremony for a key section of the Belt Road No. 4 – Ha Noi Capital Region expressway, one of the largest infrastructure projects in northern Viet Nam, with a total investment of more than VND56 trillion (around US$2.2 billion) on September 6 in Noi Bai commune.

The Ha Noi People's Committee, the city's Transport Project Management Board, and the Ha Noi Belt Road 4 Expressway JSC jointly broke ground for Component 3 of the project. This section will be built under a public-private partnership (PPP) model.
The expressway will stretch more than 113 km, including 103.8 km of the main route and 9.7 km of connecting roads toward the Noi Bai–Ha Long expressway. It is expected to be completed in 30 months.
The project includes 13 elevated sections totaling 81 km, three major bridges across the Red River – Hong Ha, Me So, and Hoai Thuong – as well as eight interchanges and one fully completed junction. In its first phase, the road will have four lanes and a width of 17 meters.
Chairman of Ha Noi People's Committee Tran Sy Thanh stated that the investing in the construction of Ring Road 4 is especially vital and urgent in order to enhance inter-provincial traffic and develop further socio-economic corridor, while also expand areas of investment and reduce population density in urban area.

The project will serve to reduce traffic passing through the city Centre, especially the currently overloaded Ring Road 3. This will also be additional motivation to develop the available land alongside the route and effort toward lowering pollution and traffic congestion.
This is the central component of the entire Ring Road 4 project, implemented under the PPP model to mobilize resources and demonstrate the collaboration between the government and investors.
The Belt Road No. 4 will link Ha Noi directly with Hung Yen, Bac Ninh, and other neighbouring provinces, while connecting with existing radial expressways to form a modern, synchronised transport network for the Red River Delta, he emphasised.
Approved by the National Assembly in June 2022 and greenlit by the Government shortly after, the project is seen as a new driver of growth. Once operational, it will not only ease congestion on existing roads, particularly the overloaded Belt Road No. 3, but also open up space for new urban, industrial, and logistics zones along the corridor.
Construction of parallel roads, bridges, and drainage works is already underway, with overall progress reaching 52.6 percent of contract value. Ha Noi leads with 70 percent completion, followed by Hung Yen at 45 percent and Bac Ninh at 34 percent. The parallel roads are expected to be largely completed in 2025 and fully finished by the first quarter of 2026.
This is the first time Viet Nam has applied the PPP model by dividing the project into smaller sub-projects, combining public investment with private capital. The groundbreaking comes as the country accelerates infrastructure development in line with the goals set out by the 13th National Party Congress.
With Belt Road No. 4 and the planned Belt Road No. 5 which is expected to link five northern provinces by 2030, Ha Noi and its surrounding region are on track to develop a modern, interconnected transport system that will cut travel times, reduce logistics costs, and drive sustainable urban growth./.
