Early in the morning on July 4, 2026, a traffic collision occurred on the Interstate 10 West on-ramp at Cherry Valley Boulevard. The incident involved an unknown type of vehicle that hit a guardrail, causing it to protrude into the second lane, and an SUV that blocked lanes. A second vehicle, which had a flat tire, went over an embankment and collided with a metal pole, knocking the pole down and blocking the on-ramp. A female passenger in one of the vehicles was slow to respond. Caltrans was notified to address the down pole. The on-ramp intersection was closed for several hours until the roadway was cleared at 2:48 AM.
