Organizing to fill the 'death hole' on National Highway 3B in Na Ri commune

The construction unit organizes filling the hole according to the approved plan.

The project "Urgently overcome the consequences of natural disasters, ensure traffic on National Highway 3B at Km80+050" is invested by the Department of Construction, with a total investment of more than 4 billion VND from the state budget. The main goal of the project is to handle serious subsidence holes that disrupt traffic and affect people's lives.

Accordingly, the technical solution to implement is to widen the pit to create a construction surface; treat the pit by dropping steel cages filled with rubble, on average 3-4 layers to create a stable connection; fill in the rubble and manually arrange the cages to create a solid surface; restore the road surface structure with standard crushed stone and asphalt layers.

By the morning of August 2, 2025, the construction unit had released 250 rock cages and is currently continuing to implement the plan approved by the competent authority. The expected completion date is before August 31, 2025.
