At least three lanes on northbound Interstate 805 just north of Bonita Road were briefly shut down as crews battled a brush fire in a riverbed, KPBS media partner 10News reports.
The brush fire broke out just before 11:45 a.m. in a riverbed near Plaza Bonita Mall in the National City area, according to authorities.
The fire response prompted the California Highway Patrol to shut down at least three lanes on northbound I-805 heading to eastbound SR-54 after less than an hour.
Shortly before 1 p.m., CHP reported that all lanes were open to traffic.
