A brush fire broke out Thursday afternoon along the northbound shoulder of Interstate 215, just south of Los Alamos Road in Murrieta, stopping rush-hour traffic.
The blaze was reported shortly before 3 p.m., according to the Murrieta Fire Department.
According to Battalion Chief Mario Monroy, five fire engines responded and discovered two separate fires that were a couple hundred feet apart from each other.
He said it took firefighters about 15 minutes to knock down the flames. The cause of the fire was under investigation.
“It is suspicious in nature because of the two separate starting points,” Monroy said.
Traffic along the northbound I-215 was at a very slow crawl and was backing up from the 215 and 15 interchange in Murrieta.
Fire crews were going to remain on scene and several fire engines would be parked on the shoulder to control the blaze, Monroy said.
