A Ralphs big rig has reportedly overturned on the eastbound transition to the 134 Freeway from the northbound I-5.
A Sigalert was issued at about 4:38 p.m. for the transition, which is sure to snarl the evening commute.
[Update 5:15 p.m.: Emergency crews are shutting down the transition for clean up and Caltrans has been called out to set up cones and signage.]
Paramedics were called in to transport at least one person was reportedly in the truck's cab. Emergency crews are working to clear the scene.
