A significant traffic collision occurred today at the northbound junction of State Route 57 (SR-57) and Orangethorpe Avenue in Placentia, CA, causing major disruptions during the morning commute. The incident involved four vehicles: a white van, a white work truck, a Jeep, and a Ford F150. One of the vehicles was overturned, lying on its roof, which exacerbated the traffic situation.

Emergency response teams were promptly dispatched to the scene, and tow operations began for at least two of the vehicles involved. Due to the severity of the traffic incident, all lanes on the northbound side of SR-57 at Orangethorpe Avenue were closed for approximately 30 minutes, leading to significant delays and congestion in the area.

A SigAlert was issued, extending the lane closure to an hour to facilitate the safe removal of the overturned vehicle and to clear the roadway for other motorists. Traffic management units worked diligently to control the situation and direct drivers to alternate routes to minimize backup.

This traffic collision serves as a reminder of the potential for unexpected incidents on busy roadways. Drivers are encouraged to remain vigilant and patient during such events to ensure safety for all road users.
