Construction Advances on Hanoi’s Thượng Cát Bridge, with Completion Planned for 2027
Hanoi’s eight-lane Thượng Cát Bridge and its approach roads represent an investment of more than VND 7.3 trillion. Construction began on October 8, 2025. Work on the construction package has reached about VND 1.1 trillion, or nearly 20.6% of the work, and the project is scheduled for completion in 2027.
Construction of Hanoi’s Thượng Cát Bridge and its approach roads is progressing, with work underway on the bridge piers and foundations. The project broke ground on October 8, 2025, with a total investment of more than VND 7.3 trillion funded by the Hanoi municipal budget. The bridge is designed with eight lanes: six for motor vehicles and two for non-motorized vehicles. Once completed, it will form part of Hanoi’s Ring Road 3.5 and provide another crossing over the Red River.

The project is more than 5.2 kilometers long, comprising approximately 3.9 kilometers of bridge and 1.3 kilometers of approach roads. The section crossing the Red River is 780 meters long and has three major spans. The bridge features V-shaped cable-stayed towers, whose structure and staged construction pose demanding technical requirements. More than 50 workers are building the pier shaft and crossbeam at pier P29. Each section takes 10 to 20 days to complete, depending on its dimensions and structure.

Construction of the piers in the river is affected by natural conditions. Rainy-season flooding raises the Red River’s water level, affecting some foundation work and requiring the contractor to adjust its construction schedule to conditions on site. Cấn Mạnh Hùng, construction manager for the package, said a single pier footing requires nearly 5,000 cubic meters of concrete. Material supplies, fuel prices and staffing are also putting pressure on construction.
The contractor is adding equipment and workers and making use of favorable weather to advance construction and make up for delays. Work completed under the construction package is currently valued at about VND 1.1 trillion, equivalent to nearly 20.6% of the work. The project is scheduled for completion in 2027.
