$1.3mn viaduct nears completion at major landslide site on Mimosa Pass in Vietnam’s Lam Dong

The project is nearly 80 percent complete.

Workers were accelerating construction at the site on National Highway 20 on Thursday.

Teams from Tien Thanh Construction Project Company and Construction and Investment 492 Company were working at full pace to complete the bridge deck, side barriers, and final components.

In just over 50 working days, excluding the nine-day Lunar New Year holiday break, from February 14 February 22, the structure has taken clear shape.

Three bridge spans, stretching more than 108 meters, now stand in place of a section of roadway that was torn apart by natural disasters.

In late November 2025, prolonged heavy rains triggered a serious landslide on Mimosa Pass.

The road surface collapsed entirely, leaving a chasm more than 70 meters wide and some 30 meters deep.

The landslide disrupted traffic flow into Da Lat.

Facing an urgent need to restore connectivity, the Ministry of Construction and the provincial People’s Committee decided to build a viaduct rather than implement temporary reinforcement measures.

Bui Huy Khoa, director of Tien Thanh Construction Project Company, said that the project has a total length of 133 meters, including access roads, with the main bridge section measuring 108 meters long and nine meters wide.

The project carries a price tag of over VND33 billion.

The viaduct is expected to open to technical traffic at the end of March, Khoa said.

He attributed the accelerated pace to expedited procedures.

Mimosa Pass serves as a priority route for trucks, large passenger buses, and heavy transport vehicles traveling from Ho Chi Minh City and southeastern provinces to Da Lat.
