The larger of the two projects is the National Highway 1A urban corridor redevelopment project, which carries a total investment of nearly VND162 trillion ($6.14 billion) and is being built by conglomerate Vingroup (HoSE: VIC).

The 36.3 km corridor will stretch from Hanoi’s Ring Road 1 near the Kim Lien tunnel to the Cau Gie interchange in the southern outskirts of the capital, passing through 18 wards and communes.

The project is designed as a major urban transport axis with a cross-section of up to 90 meters, including 10 lanes on the main route and six parallel lanes on both sides. The road is designed for speeds of up to 80 kilometers per hour.

Authorities expect infrastructure construction to be completed by 2027 as part of Hanoi’s long-term master plan, which envisions urban development over a 100-year horizon.

City officials said the project is intended to become a new economic growth corridor for southern Hanoi, supporting logistics, trade, services, and urban redevelopment while easing congestion along one of Vietnam’s busiest transport arteries.

Separately, a groundbreaking ceremony for the Nui Thoong high-tech waste treatment and waste-to-power plant in Xuan Mai commune took place on the same day. The project is valued at VND5.25 trillion ($199 million) and is being developed by Xuan Mai Urban Environment Company and Green Marble JSC.

The facility is designed to process 2,000 tons of waste per day and generate 45 megawatts of electricity, making it the first high-tech waste-to-energy plant in southwestern Hanoi.

Once operational, the plant is expected to process around 660,000 tons of waste annually and feed approximately 356 million kilowatt-hours of electricity to the national grid.

Hanoi releases more than 8,000 tons of waste daily. While the city already operates waste-to-energy plants in Soc Son and Xuan Son, authorities estimate that roughly 1,500 tons of waste per day still end up in landfills.
