CASTRO VALLEY, Calif. (KRON) — The Alameda County Fire Department fought a 58-acre fire that started on Monday. The fire was at westbound Interstate 580 and Eden Canyon Road in Castro Valley.

As of about noon on Tuesday, forward progress on the fire had been stopped and the fire was 100% contained, according to a tweet from CAL FIRE SCU. The final acreage on the fire was 56.2 acres. No structures were damaged and no one was injured.

Some structures off of Schaeffer Ranch Road were threatened by the fire, according to Cal Fire. People living west of Schaefer Ranch Road were told to be prepared to evacuate in case the fire continues to grow.

The City of Dublin used the Shannon Community Center as an evacuation center and family reunification zone. The community center is located at 11600 Shannon Avenue.

According to California Highway Patrol, the reporting party believes that the fire started when a car’s gas tank caught on fire. Two lanes on the highway were blocked. Dublin Boulevard was also temporarily closed.

The fire spread quickly. It was initially reported at three acres and has since grown to 58.
