Nguyen Van Vinh, deputy director of Khanh Hoa Province's Department of Construction, said on September 19 that contractors were working to repair the remaining landslide sites along National Highway 27C, with completion targeted for October.
Most of the damage occurred during heavy rains and flooding in late 2025. Contractors initially cleared fallen soil and rocks and carried out temporary reinforcement to keep traffic moving.
Khanh Hoa Province allocated more than VND 100 billion (USD 3.8 million) earlier this year for repairs and reinforcement along the route, including stabilising cut and fill slopes and improving road safety infrastructure.
At two locations, Km44+500 and Km44+920, slopes have been reinforced with high-strength steel mesh and rockfall barriers to prevent debris from falling onto the road.
Temporary traffic closures remain in place while slope reinforcement is carried out at the two sites. The closures are scheduled during off-peak periods and last no more than an hour at a time.
Le Thuan Doan, director of Khanh Hoa Road Construction Company, said the mountainous terrain and limited working space were complicating repairs, while contractors also had to keep the road open to traffic.
Work is further constrained by weather conditions, with sunshine often giving way to rain in the afternoon.
More than 70 workers and 20 pieces of machinery are being deployed to repair landslide damage on Khanh Le Pass, with work expected to be completed in October.
National Highway 27C stretches more than 120 kilometres between Nha Trang in Khanh Hoa Province and Dalat in Lam Dong Province. The route crosses the winding Khanh Le Pass, whose highest point is more than 1,700 metres above sea level.
Nearly 100 landslide sites were recorded on the pass in late 2025. One major rockslide killed six people and injured 18.
