Repair work on the culvert causes a 4km traffic jam on National Highway 20.

Hundreds of vehicles were stuck in a traffic jam stretching approximately 4km on National Highway 20, in the section passing through Dai Lao commune, Bao Loc city (Lam Dong province), due to an emergency repair of a culvert across this vital highway.

On the morning of June 28th, traffic through Dai Lao and Loc Chau communes (Bao Loc City) was one-way only. Hundreds of vehicles traveling from Da Lat to Ho Chi Minh City lined up, stretching for about 4km from the B'Lao Sre intersection (Dai Lao commune) to the center of Loc Chau commune.

On the Ho Chi Minh City to Da Lat route, traffic was also severely congested, stretching for more than 3km, from the B'Lao Srê intersection to the area around the Virgin Mary statue on the Bao Loc pass.

Traffic jams stretched for about 4km on National Highway 20, the section passing through Da Lao and Loc Chau communes, Bao Loc City.

The reason is that the culvert at the B'Lao Srê intersection (Dai Lao commune) had to be repaired unexpectedly, causing vehicles to only travel in one direction under the regulation and guidance of traffic police.

This traffic congestion started at 2 AM this morning and shows no signs of easing. On average, each vehicle takes 1 to 1.5 hours to travel through the Bao Loc pass.

The traffic congestion was caused by unscheduled repairs to a culvert on National Highway 20.

The traffic police team stationed at Bao Loc Pass, under the Madagui Station of the Lam Dong Provincial Police Department's Traffic Police Division, deployed numerous officers to regulate, reroute, and guide vehicles to move in an orderly manner through the culvert under repair. Due to the rain and the heavy traffic on the weekend, traffic regulation and rerouting faced many difficulties.

Traffic police are directing traffic through the congested area.

Emergency repairs to the culvert at the B'Lao Srê intersection on National Highway 20 commenced in late June 2025. In addition to this location, the Bảo Lộc pass has recently experienced frequent and prolonged traffic congestion due to repairs to the Bảo Lộc 2 bridge. The peak was on June 8th, when traffic on National Highway 20 and the Bảo Lộc pass was blocked for over 10km, lasting for many hours.
