On the afternoon of 25/9, the People's Committee of Xuan Huong Ward, Da Lat, and related agencies inspected the site, confirming a crack about 40 m long running along the road surface, extending nearly across one lane.

To mitigate safety risks, authorities cordoned off the area, installed warning signs, and directed vehicles entering and exiting Da Lat to the uphill side of the road. Tarpaulins were laid along the crack to prevent water from seeping into the roadbed during ongoing rains.

This site is about 200 m from a section of Mimosa Pass that fractured and slid down the downhill slope late last year. That damaged area was later repaired with the Xuan Huong viaduct.

Project Management Board 85, under the Ministry of Construction, attributes the crack's initial appearance to storms and heavy rains late last year. Recent prolonged heavy rainfall has caused the crack to widen, raising concerns about potential landslides and abrupt collapses of the roadbed and surface towards the downhill slope, endangering commuters.

Mimosa Pass, spanning 11 km on national highway 20, serves as one of Da Lat's southern gateways, alongside Prenn Pass and Sacom Pass (which is restricted to trucks).

In recent days, heavy rains have triggered numerous landslides across Lam Dong province. Notably, Prenn Pass, Dai Ninh Pass, and Gia Bac Pass have experienced multiple closures and traffic diversions. Several areas have also reported land cracks, subsidence, and flooding.
