A semi-truck hauling concrete blew a tire and flipped onto its roof on westbound Interstate 10 near Dillon Road shortly after 9:30 a.m. Wednesday, spilling concrete across the freeway near Spotlight 29 Casino and forcing officers to shut down the roadway while crews worked to clear the mess.
The driver was taken to the hospital with minor injuries, NBC Palm Springs reported. Caltrans crews worked to clear the roadway while Cal Fire responded to contain a diesel spill from the overturned rig, per the same outlet's report. A heavy-duty tow truck was being brought in to remove the rig from the roadway.
Traffic was moving through the side lanes near Dillon Road as crews worked the scene, though the station's report noted that delays were expected to continue significantly. Drivers were advised to avoid the area if possible and allow extra time for their commute.
A Freight Corridor Under Strain
Commercial rigs like the one involved Wednesday are also subject to tire tread standards. California law requires at least 2/32 inch of tread depth, while 4/32 inch on steer tires is a best-practice replacement threshold, according to AUTOsist.
Interstate 10 through eastern Riverside County carries roughly 35,000 vehicles a day, with commercial freight trucks making up approximately 35% of that traffic, per data cited by Roads & Bridges. That same outlet notes Caltrans District 8 completed a multi-million-dollar rehabilitation project east of Coachella in December 2025, including full-depth pavement reconstruction and a new eastbound truck-climbing lane.
Earlier Crashes Near Dillon Road
The Dillon Road stretch of I-10 has seen several major incidents over the past year and a half. In March 2025, a semi-truck rolled over east of Dillon Road, requiring firefighters to extricate a driver with minor injuries and shutting eastbound lanes for about three hours, according to MyNewsLA.
In April 2026, a head-on collision on eastbound I-10 east of Dillon Road killed three people after a 71-year-old driver entered the freeway going the wrong direction, according to KESQ.
