When the rainy season comes, National Highway 46B passing through Nguoc Mountain, Thanh Chuong District often experiences serious landslides. The landslide treatment project under construction here will help eliminate the traffic black spot in Nguoc Mountain.

National Highway 46B through Nguoc Mountain is quite dangerous because one side is a high mountain and the other side is a deep river. During the resistance war against the US, the route through Nguoc Mountain was fiercely bombarded by the enemy. Today, this route is still a traffic black spot. Photo: Huy Thu

In recent years, during the rainy season, landslides often occur at Nguoc Mountain. In particular, in 2020, Nguoc Mountain had a serious landslide with a length of nearly 2 km, completely blocking National Highway 46B. After each landslide, the authorities have handled and resolved the incident, such as blasting rocks, erecting steel nets, embanking rivers, making ditches, adjusting roads... Photo: Huy Thu

The large-scale handling of landslides in Nguoc Mountain, aiming to create a safe road section, minimizing landslides every rainy season is not only the desire and expectation of traffic participants on this route but also of local people. Photo: Huy Thu

Currently, the project "Landslide treatment section KM39 +200 - KM39 +750 National Highway 46B, Nghe An province" invested by Road Management Area II is being constructed in Nguoc mountain. The construction site is located in Thanh Ngoc commune (Thanh Chuong). Photo: Huy Thu

A landslide-prone area at Nguoc Mountain (which used to be protected by steel mesh) is being lowered. According to construction units, machinery and equipment are currently working quite smoothly. During the process of cutting the mountain, if large rocks are encountered, a permit will be obtained from the authorities to blast rocks. Photo: Huy Thu

Nguoc Mountain will be sloped in steps (from 2 to 6, 7... steps) depending on the location and height of the mountain to prevent landslides. Power lines on the mountain that affect the construction work will be moved up. Photo: Huy Thu

There are large rocks that rolled down the mountain into the river, not stuck on the road. People and vehicles passing through here need to observe carefully. Construction units also need to increase water spraying to prevent dust and environmental pollution. Photo: Huy Thu

Strictly following the regulations of the construction site will contribute to maintaining general safety for everyone. Photo: Huy Thu

Mr. Le Dinh Thanh - Vice Chairman of Thanh Chuong District People's Committee said: "The anti-landslide project at Nguoc Mountain is very important for the travel of Thanh Chuong district people, because this is the main road connecting Thanh Chuong district with Vinh city and neighboring areas. For that reason, when the Department of Roads had a policy to handle this section, the District People's Committee actively coordinated to clear the site and hand over the clean site to the investor for implementation. The completed project will help vehicles to travel through this section more conveniently, especially when the rainy season comes". Photo: Huy Thu
