One lane of Placerita Canyon Road is being used to funnel traffic past a landslide that covered Placerita Canyon Road with boulders as large as 4 1/2 feet high.

The California Highway Patrol is directing traffic through the affected area, which is approximately one mile east of the 14 Freeway, near the Placerita Nature Center.

Ranger Frank Hoffman from Placerita Nature Center said that some traffic is slowly being escorted through. The landslide did not affect anyone at the Center and no injuries have been reported.
