A traffic collision on Interstate 5 North in Chula Vista, CA, caused significant disruptions during the early morning hours today. The incident, involving two vehicles—a black BMW and an unknown vehicle—occurred around 3:09 AM, leading to multiple lane closures that impacted traffic flow on Palomar and adjacent roadways.

Emergency response units were quickly deployed to manage the scene and control traffic. The collision resulted in the closure of several lanes, particularly the slow lane, creating delays for early morning commuters. A tow truck was called to remove one of the vehicles involved in the incident, which was obstructing the roadway.

By 4:04 AM, authorities reported that one lane was reopened, but the second, third, and fourth lanes remained closed, along with the L Street off-ramp. Traffic congestion was evident as vehicles were diverted, leading to backups in the area. The California Highway Patrol issued a SigAlert, indicating that the closures would last for approximately one hour.

As crews worked diligently to clear the scene and restore normal traffic conditions, all lanes, including the Palomar on-ramp, were confirmed cleared by 5:38 AM. Motorists are advised to exercise caution in the area and anticipate potential delays as cleanup efforts were underway.
