A tractor-trailer and four other vehicles collided Tuesday on the Pomona (60) Freeway in Jurupa Valley, injuring three people and forcing a closure of all westbound lanes that lasted more than 90 minutes.
The crash happened at 3:33 p.m. on the westbound 60 at Valley Way, according to the California Highway Patrol.
The agency said the semi, several sedans and a pickup truck collided in the middle of the freeway, but no other details were immediately available.
The big rig stalled, blocking at least three of five traffic lanes, while wreckage and fluids from the other vehicles was hurled into adjacent lanes, the CHP said, resulting in obstructions blocking the entire westbound side of the freeway.
A SigAlert was issued at 3:54 p.m. because of the ensuing traffic jam extending south of the 60/91/215 interchange.
At 5:10 p.m., all wreckage had been cleared and absorbents dispersed over the fluids, rendering the freeway safe and enabling the lane closures to be lifted, the CHP said.
Riverside County Fire Department crews reached the location just after 4 p.m. and found all of the motorists involved in the collision outside of their vehicles. Three of them suffered minor injuries and were taken to Riverside Community Hospital in stable condition.
The cause of the collision was under investigation.
