Hanoi Department of Construction has released a detailed 1:500 scale plan for two new arterial boulevards running parallel to the Red River (Sông Hồng), inviting public comments until 26 September.
Together the routes will cover roughly 80 kilometres, forming the core of the larger 1:5,000 master plan for the Red River urban sub‑district.
On the north (tả) bank
A 35‑km stretch will start at the Hồng Hà bridge in Mê Linh, pass through Đông Anh and Long Biên, and terminate at Bát Tràng, linking with Hưng Yên’s heritage corridor.
The south (hữu) bank line
The south line runs about 45 km from the Hồng Hà bridge in Ô Diên to Ring Road 4 at the Mễ Sở bridge in Hồng Vân. Both corridors are designated as primary city arteries with six main lanes designed for 80 km/h, plus up to four collector lanes limited to 60 km/h. Widths vary from 54 to 73.5 m, with main sections 40‑50 m wide for six‑to‑eight lanes and narrower 17.5‑30 m segments for two‑to‑four lanes where space permits.
Key engineering adaptations
Key engineering adaptations include narrowed sections near cultural sites on the north bank and a 2.3‑km underground tunnel (hầm kín) from Long Biên bridge to after Chương Dương bridge, mirrored by a tunnel proposal on the south bank near Long Biên. The boulevards will interconnect with major bridges—Thăng Long, Nhật Tân, Long Biên, Chương Dương, Vĩnh Tuy—and the city’s ring‑road network, integrating road, waterway and upcoming metro lines while enhancing flood‑resilient infrastructure.
Institute of Planning and Construction of Hanoi highlighted that existing embankment roads, only 3.5‑7 m wide, are inadequate for motor traffic, prompting the comprehensive upgrade.
After the consultation period, the department will consolidate feedback and assess environmental and heritage impacts before proceeding.
