A fatal collision involving multiple vehicles-including a semi truck-shut down most of the northbound 5 Freeway in Santa Clarita before dawn Tuesday, snarling the morning commute.
Crash Details
The California Highway Patrol received reports of the wreck around 3 a.m. just south of Magic Mountain Parkway. Officers confirmed the pile-up involved several passenger cars and at least one big rig.
Emergency crews pronounced one person dead at the scene. Authorities have not released the victim’s identity or specified what triggered the collision.

The wreckage blocked all but a single lane, forcing the CHP to issue a Sigalert for the area. Northbound traffic is being diverted off the freeway at Valencia Boulevard, creating a bottleneck that stretches for miles.
- Expect up to 60 minutes of extra travel time
- Alternate routes via Sierra Highway and McBean Parkway are strongly advised
- Caltrans crews are on scene clearing debris and repairing guardrail damage
