Overturned big rig at I-5, 134 Fwy. transition to snarl evening commute [Updated]

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.
