A section of the damaged road on the Prenn Pass under repair.
A landslide on November 17 forced the provincial people’s committee to declare a state of emergency and close the four-lane mountain road to all traffic.
According to the provincial department of construction, heavy rain and storms continue to pose risks across the area, while contractors are still carrying out repairs and restoration work.
The department advised drivers to avoid travelling through the Prenn Pass during heavy rain, at night or when visibility is low due to fog, except in essential cases. Motorists are urged to stay alert to road conditions and be ready for potential incidents.
Vehicles should travel slowly, follow traffic signs and temporary diversions, and comply with safety instructions at active construction sites.
The provincial traffic police division and the Xuan Huong-Dalat Ward People’s Committee have been asked to maintain regular patrols to ensure safe traffic flow during the repair period.
During a Tuesday meeting on repairs to storm- and flood-damaged transport infrastructure, vice chairman Nguyen Hong Hai instructed agencies to prioritise handling subsidence along the Prenn Pass.
He assigned the department of construction to reopen the route in two phases: phase one, the temporary reopening before 1 pm on Tuesday; and phase two, full reopening before the Tet Holiday around February 10, 2026, once all landslide and road-surface repairs are complete.
When repairs are finished, the department of construction will take over long-term management of the route.
The Prenn Pass upgrade and expansion project, launched on February 10, 2023, spans 7.4 km with a four-lane design, a 15.5 metre roadbed and a 14.5 metre carriageway. The project has a total investment of VND 553 billion from the provincial budget and is scheduled for completion in 2022-2023. It is a key gateway linking Dalat with Lien Khuong International Airport.
Currently, four routes connect Dalat with southern provinces, but the two most important ones, Prenn Pass and Mimosa Pass, have both suffered serious subsidence and remain under a state of emergency due to natural disasters.
