SAN DIEGO -- The San Diego Fire-Rescue Department responded to a series of small spot fires near the junction of state Route 905 and Interstate 805 in the San Ysidro area Sunday.
SDFD told FOX 5 shortly before 7 p.m. that the fire was caused by a faulty catalytic converter.
The San Diego Police Department had detained two people in the area near the blaze. One was released from custody and the other was arrested for being under the influence, according to SDPD.
California Highway Patrol shut down portions of both freeways and crews put out the blaze within about an hour.
During the battle, the I-805 connector to eastbound SR-905 was closed, and eastbound traffic was diverted off to Picador Blvd due to heavy smoke. No structures were reported damaged and no one was injured.
Shortly before 4 p.m., Caltrans announced the 805-905 connector had reopened.
The series of small fires burned about a mile and a half of grass and brush along the 905.
