A jack-knifed big-rig on the northbound I-15 Freeway near SR 79 south has reportedly caused a major back up through the Temecula Valley.
Northbound traffic is backed up several miles, with evening commuters stuck in heavy congestion well past the Rainbow Valley Boulevard exit. Southbound traffic is backed up in the area as well, with commuters slowing to see the activity along the other side of the freeway.
CHP officials are on scene and working to clear the roadway and ease congestion through the area.
This is a breaking news story and will be updated as more information becomes available.
