ONTARIO, Calif. () — One person was killed Thursday morning in a multi-vehicle crash involving a semi-truck on 10 Freeway in Ontario that forced a closure of all westbound lanes that lasted several hours, authorities said.
The crash was reported shortly after 3 a.m. at the 15 Freeway connector, according to the California Highway Patrol.
A preliminary investigation indicated that a Kenworth tractor pulling a flatbed trailer combination carrying a large excavator, traveling westbound in the No. 3 lane, crashed into the 15 Freeway overpass at the scene, according to the California Highway Patrol.
This caused a metal beam to fall from the overpass onto a vehicle, a Toyota Camry, also traveling westbound on 10 Freeway in the No. 1 lane, the CHP said in a press release. A third vehicle, a Honda Accord also traveling westbound on 10 in the No. 2 lane, subsequently hit the fallen beam.
“They were transferred to [Arrowhead Regional Medical Center] by emergency personnel for major injuries, and unfortunately one of the drivers passed away,” said CHP Ofc. Joe Garcia.
The driver who died was identified only as a woman.
Meantime, the driver of the tractor, a 50-year-old man from Mira Loma, stayed at the scene throughout the investigation, according to CHP. Investigators said alcohol or drug impairment is not suspected to be a factor in this crash.
The crash shut down all westbound lanes, causing significant backup for drivers in the area. The CHP initially said lanes would reopen by 4:30 a.m., but the closure was extended throughout the morning.
The freeway reopened Thursday afternoon.
