Landslide closes 10 Freeway interchange in Pomona [Updated]
A hillside near the 10 Freeway and Highway 57 in Pomona collapsed Thursday, shutting down two interchanges as dirt and large rocks tumbled into traffic lanes, authorities said.
Boulders were reported sliding down the hillside about 8:30 a.m. near the westbound 10 Freeway transition to northbound Highway 57, and a light pole was lying in the road, said California Highway Patrol Officer Francisco Villalobos.
Part of Highway 71 to the northbound Highway 57 also was closed.
Caltrans crews were en route to the scene. Villalobos did not know when the roads would be reopened. [Updated at 10:42 a.m.: CHP officials said the interchanges will remain closed for up to a week while crews work to repair the sinkhole and clean up the debris.] Investigators were trying to determine what triggered the slide.
