By 4:30 p.m., the winds shifted and caused the fire to burn back toward the eastbound side of the 91 Freeway. Firefighters were burning fuel along the freeway near the roadway to keep the blaze from spreading into the area.
There were more than 150 firefighters on the ground, along with five water-dropping helicopters and three fixed-wing aircrafts, authorities said.
Traffic was heavily impacted as Caltrans officials closed three of seven lanes on the eastbound 91 just east of Coal Canyon Road.
The blaze was moving so quickly, it was making its way into Chino Hills State Park from Pipeline Road.
Orange County Fire Authority officials said over 100 firefighters were battling the blaze from the ground. Five water-dropping helicopters and three fixed wing planes were assisting in the firefight from the air.
The cause of the fire was under investigation.
