The 120 year old bridge underwent maintenance to address wear and tear, including damaged road surfaces, corroded steel components and deteriorated railings that had affected traffic safety.
Construction began in late October, when sections of the bridge were cordoned off for periodic maintenance to ensure the safe operation of the Hanoi-Dong Dang railway line.
From November 1, the lane for non motorised vehicles in the direction from Bo De ward to Hoan Kiem Ward was closed for 61 days.
Crews from the Railway Construction Company worked continuously on the bridge deck and steel framework, removing degraded components and reinforcing the structure with new materials.
Damaged concrete deck slabs were replaced section by section to improve surface evenness and load bearing capacity.
Corroded steel parts were cleaned, repaired or replaced, while joints and key load bearing points were reinforced to enhance durability and safety.
Repairs were also carried out beneath the bridge, focusing on areas considered potentially hazardous within the confined working space.
The project has now entered its final stage, with several sections already resurfaced.
Workers are dismantling construction equipment and clearing the site ahead of reopening.
New components have been installed on the bridge railings and coated with protective paint to help preserve the structure.
A historic and architectural landmark of Hanoi, Long Bien Bridge remains a popular destination for residents and visitors, offering views of the Red River and insights into the city’s past.
After 61 days of repairs and a period of one way operation, the bridge will resume two way traffic on January 1, 2026.
