HCM City (VNS/VNA) - A key section of the Ho Chi Minh City - Long Thanh - Dau Giay Expressway will be partially closed for maintenance until mid-August, as authorities carry out structural repairs and upgrades to the route’s Intelligent Transportation System (ITS).
According to the Vietnam Expressway Services Engineering Joint Stock Company (VECE), which operates the 55-km expressway, repairs began on July 15 and include replacement of expansion joints on the Long Thanh Bridge and maintenance of the expressway’s ITS.
Work on the bridge’s P26 pier joint is expected to take 15 days, during which half of the left-side carriageway (in the Dong Nai–HCM City direction) will be closed. Speed limits will be reduced in affected zones.
Separately, ITS upgrades will be conducted at 64 points along the expressway, with lane narrowing and lower speed limits in place until mid-August.
VECE has warned of potential congestion during the construction period. Drivers are urged to slow down, maintain safe distances, and check traffic updates for alternative routes.
Police and traffic controllers will be deployed at key points to manage traffic flow.
Critical infrastructure
Launched in 2015, the four-lane HCM City - Long Thanh - Dau Giây Expressway connects HCM City to Dong Nai province, with links to industrial zones, ports, and major highways in southern Vietnam.
It features two emergency lanes and supports a design speed of 100 km per hour.
The Long Thanh Bridge, the largest and most complex structure on the route, spans 2.3 km and was last repaired in September 2024.
It is a frequent congestion point, particularly on weekends and holidays.
Traffic volumes have surged since the expressway was connected to the Dau Giay–Phan Thiet Expressway, with further increases expected once it links to the Bien Hoa–Vung Tau Expressway and the under-construction Long Thanh International Airport.
To ease pressure, the Government plans to start a major expansion next month, widening a 22-km section from HCM City’s Ring Road 2 to the Bien Hoa-Vung Tau interchange./.
