Ontario, CA (January 17, 2026) — A tragic chain-reaction crash on the 10 Freeway early Thursday morning left one person dead and several others injured after a semi-truck struck a bridge structure, causing a steel beam to fall onto the freeway in Ontario.
According to the California Highway Patrol, the incident happened at approximately 3:19 a.m. on January 15 when a big rig hauling heavy machinery collided with overhead steel girders near the 15 Freeway Express Lanes and Freight Corridor construction project. The impact dislodged a support beam, which crashed onto the westbound lanes of Interstate 10, where multiple vehicles collided with the debris.
One of the victims was transported to a nearby hospital and later pronounced dead. Several others were injured and treated at local facilities. Authorities issued a SigAlert shortly after the incident, shutting down all westbound lanes of the 10 Freeway. Cleanup, investigation, and structural assessments are ongoing, with partial lane reopenings occurring late Thursday morning.
