After Typhoon Yagi, according to a report from the Quang Ninh Department of Transport, there were 267 landslides, including 80 negative slopes and 217 positive slopes, 1,101 road sign posts were damaged. 16,770 trees were broken, 80 lamp posts and electric poles were damaged, and serious damage was caused to toll stations and expressway operators with a total loss of 47.4 billion VND.
Up to now, the roads have basically been repaired and traffic has returned to normal. However, for provincial road 342 (Ha Long), due to negative slope landslides, the Department of Transport has banned trucks over 3.5 tons from circulating from Km18+180 - Km32+00, while other vehicles are still circulating normally. On National Highway 18B, section Km10+390 through Hai Ha district, since September 20, after receiving an order to build an emergency project from the Ministry of Transport, repair work is being carried out.
On the morning of October 18, according to the reporter's observation at the scene of the landslide on Highway 18B, the roadbed compaction operation was taking place urgently. Some motorbikes were able to circulate.
Mr. Bui Hong Minh, Deputy Director of the Department of Transport of Quang Ninh, said: "With the current progress, we expect to open the route on October 20, helping people and vehicles return to normal traffic."
Previously, heavy rain on August 20, 2024 caused a landslide of about 30m long and 20m deep, causing 2/3 of the road surface to slide into the abyss and the drainage culvert to break, cutting off the road connecting National Highway 18 to Bac Phong Sinh border gate (Hai Ha).
To ensure traffic, authorities have set up checkpoints and divided traffic into three directions: heavy trucks move through National Highway 18C from Km4 Mong Cai to Bac Phong Sinh border gate, other vehicles can go through Binh Lieu district or Quang Duc commune.
Mr. Nguyen Hong Nam, a driver of Vietway Joint Stock Company (residing in Quang Duc commune, Hai Ha district), shared: "I monitor the construction progress here every day, currently high-chassis cars can travel. When there is a landslide like that, I have less work to do, because the detour from Km4 Mong Cai to Bac Phong Sinh border gate is more than 60km away, the additional costs, import-export enterprises also have to recalculate, waiting for the road to be cleared to continue exporting goods".
The estimated cost of repairing landslides on National Highway 18B is about 4 billion VND. Of which, the cost of filling soil to restore the slope is 189 million VND, the cost of the cross-road culvert system is 2.272 billion VND, and the cost of constructing other items such as downstream water levels, stone cages, and concrete retaining walls is nearly 1 billion VND in total.
