POMONA, Calif. (KTLA) — Traffic was reduced to a crawl on the 60 Freeway in Pomona for several hours Thursday morning after an accident involving two big rigs.
It happened around 3 a.m. on the eastbound 60 at the connector to the 71 Freeway, according to the California Highway Patrol.
CHP officials said the driver of an empty car hauler may have fallen asleep and then rear ended a tractor-trailer.
One of the drivers was taken to the hospital for treatment of minor injuries.
There was also a secondary crash involving a Kia sedan and an SUV that were trying to avoid the initial wreck.
Only the far right lane was open to traffic for several hours while crews worked to clear the scene.
A crane had to be brought in to remove the trailer portion of the tractor-trailer, which had separated from the rig.
All eastbound lanes were finally reopened shortly before 8 a.m., but traffic remained slow.
Elsewhere, traffic was snarled in Downey after a big rig spun out and jackknifed on the transition from the southbound 605 Freeway to the westbound 105 Freeway.
The Sig Alert was expected to last until at least 9 a.m., putting a pinch on the 5 and 605 freeways.
