The 60 Freeway was closed in both directions in the area, Cal Fire said.
A nursing center was evacuated as flames on a hillside inched closer to the area, sending plumes of smoke shooting into the sky. Senior patients, many of them in wheelchairs and several others on stretchers, were taken out of the facility by healthcare workers.
Groups of patients wearing face masks were seen waiting for transportation near the Pedley Road off-ramp as winds whipped up thick smoke.
