As the rainy season raises landslide risks on mountain passes, Lam Dong is strengthening safety measures to keep key tourist routes open and secure.

Concerns Along Mountain Passes
The rainy season poses significant challenges for transportation in Lam Dong Province, particularly on mountain passes where steep terrain and prolonged rainfall increase the risk of landslides.

Along National Highway 28B, a key route currently undergoing expansion and upgrading to improve connectivity between the coastal and highland regions of Lam Dong, several vulnerable sections have already been identified. Areas on the slopes above the road have experienced soil and rock movement near the roadway, especially between Km31 and Km52 along Dai Ninh Pass, which is considered highly prone to landslides during extended periods of heavy rain.

Local resident Tran Thanh Cong noted that recent road improvement works have widened many sharp curves along Dai Ninh Pass, making travel safer and more convenient. However, large exposed rock formations remain on some slopes, and around ten landslide incidents were recorded along this route in 2025.

Heavy rainfall and dense fog in the Dai Ninh Pass area can significantly reduce visibility, affecting driving conditions, especially for passenger buses and heavy trucks.

Tour bus driver Cap Van Tuyen, who frequently operates between Ho Chi Minh City and Lam Dong, said heavy rain and dense fog often reduce visibility on the pass, creating additional risks for passenger buses and freight vehicles. He called for continued monitoring of landslide-prone areas and the installation of additional warning signs.

Other important routes, including National Highways 27 and 28, as well as Bao Loc Pass and Gia Bac Pass, also face similar challenges during the rainy season. In 2025, prolonged rainfall triggered multiple landslides, temporarily disrupting transportation and tourism activities.
Proactive Measures to Ensure Smooth Travel
The temporary closure of Lien Khuong Airport for maintenance has increased pressure on the province’s road network, making uninterrupted road connectivity even more critical for passenger and freight transport.

Recognizing the risks, local authorities have intensified efforts to identify vulnerable locations, strengthen preventive infrastructure, and improve emergency response capacity.

At Bao Loc Pass, road maintenance teams conduct regular inspections, clear drainage systems, maintain 24-hour monitoring, and keep equipment on standby to respond quickly to incidents.
According to Duong Nguyen Thanh, head of the road management unit responsible for a section of National Highway 20, patrols are carried out two to three times daily during the rainy season. Any landslides or road damage are addressed immediately using on-site personnel and machinery.

To proactively respond to landslide risks on Bao Loc Pass during the rainy season, the road management unit has increased patrols along the entire route to two or three times per day. Whenever damage or landslides occur, we are prepared to carry out immediate on-site repairs using available personnel and equipment.

Similar efforts are underway on National Highway 28, where local authorities regularly inspect sections with potential landslide risks.
Tran Nam Thuan, Chairman of Ta Dung Commune People's Committee, said warning signs have been installed at locations with a history of landslides, while plans are being developed to remove large rocks that could fall onto the roadway during heavy rain.

The local authorities' goal is to proactively identify potential traffic safety risks at an early stage so that timely solutions can be implemented, minimizing disruptions to residents’ travel and daily activities.

On Mimosa Pass, one of the main gateways to central Lam Dong, construction is progressing on the Mimosa Viaduct following the completion of Xuan Huong Bridge, both designed to reduce landslide risks and improve traffic safety.

Hoang Anh Tuan, Deputy Director of the Lam Dong Department of Construction, said specialized inspection teams have been deployed to monitor bridges, roads, and protective structures on major highways and mountain passes throughout the province.
The construction sector remains ready to mobilize forces and equipment to ensure roads remain open and safe during the rainy season
Emergency materials, equipment, and personnel are also being prepared in advance to ensure quick responses and prevent prolonged traffic disruptions.
Despite ongoing challenges posed by complex mountainous terrain and increasingly unpredictable weather, Lam Dong continues to follow the “four-on-the-spot” emergency response principle, ensuring that resources, personnel, equipment, and command systems are ready to keep roads open and safe throughout the rainy season.
