A large fire at a transformer site in South Bay forced dozens out of their homes and nearby businesses Saturday morning.
The electrical transformer site on 1669 Palm Ave. caught fire at about 8:10 a.m. Saturday.
Traffic on the northbound Palm Ave. offramp from the I-5. was shut down to better fight the fire, according the California Highway Patrol.
Fire crews immediately began fighting the fire at the site's relay station, but nearby businesses and residents evacuated.
At about 10 a.m., crews had knocked the fire down. They determined that a piece of equipment at the substation caught fire, but still don't know what originally caused the fire.
San Diego Fire Department and Coronado and San Diego Police Departments responded to the scene. A HAZMAT team had responded as well.
