Heavy rains from early morning on 22/11 led to significant disruptions across Central Vietnam's key transportation arteries. The area north of Deo Ca pass, through Dak Lak (formerly Phu Yen), was heavily flooded, damaging National Highway 1. This prompted traffic police to temporarily close the road for safety. Similarly, National Highway 27C, which connects Nha Trang and Da Lat, was blocked due to multiple landslides in Khanh Hoa.

Following a major incident at Deo Khanh Le pass, National Highway 27C has been closed since 17/11. Authorities are directing vehicles along two alternative routes: from Khanh Hoa via National Highway 1, National Highway 27, and the Lien Khuong - Prenn expressway to Da Lat; or via National Highway 1, National Highway 26, and National Highway 27. However, both main routes feature numerous sections with deep flooding and damage, necessitating vehicle restrictions and causing congestion at many points.

Towards Lam Dong, a 70-meter landslide on Deo Mimosa pass (National Highway 20) remains unresolved. As a result, all vehicles are being rerouted via National Highway 20, National Highway 27, and Road DT.725. National Highway 27 is becoming the primary route connecting Phan Rang and Da Lat, leading to overload due to the large volume of diverted traffic.

In Khanh Hoa, traffic police are actively managing diversions at four expressway interchanges between Phan Thiet and Nha Trang. On the Phan Thiet – Vinh Hao expressway (south-north direction), vehicles are directed onto National Highway 1 at the Ba Bau interchange (km 234). On the Cam Lam – Vinh Hao expressway, vehicles exit onto the national highway at the Phan Rang interchange (km 92). Furthermore, vehicles on the Nha Trang – Cam Lam expressway are directed to the Suoi Dau interchange (km 15); while those on the Van Phong – Nha Trang expressway turn onto National Highway 26 at km 332.

Khanh Hoa traffic police advise drivers to actively update information and choose appropriate routes, thus avoiding concentrated congestion at a single point.

According to the Vietnam Road Administration, as of 10:00 on 22/11, 17 locations on national highways in the Central region still had traffic jams and deep flooding, with the highest concentration in Khanh Hoa. Authorities are on duty 24 hours a day, continuing to manage traffic and resolve incidents.
