Accordingly, at around 8:00 p.m. on September 28, at Km110+850 on National Highway 7 passing through Boong village, Lang Khe commune (Con Cuong), landslides occurred continuously with large volumes of rocks and soil, leading to traffic congestion on this route. Some vehicles got stuck.

Immediately after the incident, Con Cuong Road Management Department mobilized excavators and human resources to promptly clear the road. However, due to the large volume of earth and rock, the bulldozers could not keep up. Therefore, to ensure the safety of people and property, Con Cuong Road Management Department closed the road from 12:00 a.m. last night until 5:00 a.m. on September 29 to handle the situation.
