Authorities have shut down a freeway transition road in Pomona because a section of a newly-repaired hillside came down and pushed concrete barriers into lanes.
The California Highway Patrol says the ramp from westbound 10 Freeway to northbound State Route 57 was ordered closed Sunday morning. Motorists called 911 to report that the regraded slope had come loose.
Authorities said the road might reopen in about two weeks.
Caltrans has equipment on the hillside to bring down more dirt and rocks that appeared close to sliding down the embankment.
The same lanes were closed for about six weeks weeks starting Feb. 18, when a large section of embankment fell onto the freeway transition road following heavy rains.
According to Caltrans, about 27,000 motorists used the transition road every day.
