A brush fire that was started by a faulty catalytic converter briefly closed the on-ramp to State Route 905 on Sunday, authorities said.
The fire was reported around 2:30 p.m. in the 4000 block of Via de la Bandola, San Diego Fire-Rescue (SDFD) spokeswoman Monica Munoz said.
"A caller was driving by when they spotted the flames in the brush," she said.
The fire was on eastbound SR-905 in the embankment to Interstate 805, Munoz said. The fire was knocked down within an hour. No one was injured and no structures were threatened, she said.
The cause of the fire is under investigation, Munoz said.
The ramp to the eastbound SR-905 from I-805 south was closed for around 90 minutes, according to the California Highway Patrol. The ramp was reopened around 4:15 p.m., the CHP said.
A suspect was detained and questioned but was released after authorities discovered the fire was accidentally started by a catalytic converter, San Diego Police Department Officer John Buttle said.
There were three spot fires reported on the side of the freeway, San Diego Police Department (SDPD) Delimitros said. Customs and Border Protection (CBP) also reported several small fires in the area, Munoz said.
It was unclear if the fires were all related.
