Evacuation orders were issued as crews battle the 50-acre Roadside Fire burning in the Cajon Pass area Saturday.
The blaze was reported around 11:25 a.m., spurring evacuation orders for all homes and businesses off Cajon Boulevard, between Keenbrook Road and Swarthout Canyon Road, according to San Bernardino National Forest officials.
“Ground crews and air support are aggressively working to suppress the fire around multiple values at risk, including structures, power lines, railroad infrastructure and more,” fire officials tweeted.
Cajon Boulevard was closed between Kenwood Avenue and Swarthout Canyon Road as crews responded.
At noon, the fire was estimated to be 10 acres in size and spreading fast as it ripped through grass and chaparral.
An hour later, the wildfire had already grown to an estimated 50 acres.
Shortly before 2 p.m., fire officials said they had the blaze “boxed in” by retardant and that crews were able to stop it from growing further.
As of 6:42 p.m., the San Bernardino National Forest reported the fire reached 30% containment.
Residents forced to flee their homes can head to the evacuation shelter at the Jessie Turner Community Center at 15556 Summit Ave. in Fontana.
The Roadside Fire is not far from the South Fire that erupted Wednesday afternoon near the 15 Freeway, in the area of Lytle Creek and Duncan roads and destroyed homes as it grew to 819 acres.
