On February 24, recording at Km226+600 – Km226+800, National Highway 20, on Mimosa Pass, the working atmosphere was urgent.
Right on the first day of returning to the construction site after Tet, the team of Tien Thanh Construction Company Limited deployed the construction of the bridge body, bridge deck and completed the remaining items.
According to the representative of the investor, after more than 50 days of actual construction (excluding Tet holiday), the project reached nearly 80% of the volume.
Three overpass girder spans on Mimosa Pass, more than 108m long, have been basically completed in the area where serious landslides occurred at the end of 2025.
Mr. Bui Huy Khoa, Director of Tien Thanh Company (construction unit), said that the project investor (name in the design documents is Xuan Huong bridge) belongs to Project Management Board 85 (Ministry of Construction) as the investor. The contractor consortium includes Tien Thanh Company and Construction and Investment Joint Stock Company 492 (Nghe An).
Mimosa Pass elevated bridge has a total length of 133m (including approach roads at both ends), the bridge section is 108m long, 9m wide; total investment of more than 33 billion VND.
The project started in mid-December 2025, and is expected to be technically opened to traffic at the end of March 2026.
Mimosa Pass is one of the two main gateways to the center of Da Lat, along with Prenn Pass, playing an important role in transporting goods, agricultural products, construction materials and passengers from Ho Chi Minh City, Southeast provinces to Da Lat and vice versa.
This is also a priority route for trucks, large passenger cars and heavy vehicles.
As Lao Dong Newspaper has reported: At the end of November and early December 2025, heavy rain caused serious landslides, causing the road surface of Mimosa Pass to subside and be damaged with a width of more than 70m and a depth of about 30m, traffic was repeatedly cut off.
Faced with the above situation, the Ministry of Construction and Lam Dong province decided to build an elevated bridge instead of a temporary reinforcement plan to ensure long-term safety for the pass route.
