Multiple fire departments responded about 7:25 p.m. Thursday to a large brush fire at the corner of Wagner Road and Imbs Station Road in rural St. Clair County.

The Columbia, Millstadt, Prairie du Pont, Villa Hills, Cahokia and Camp Jackson fire departments were among those dispatched to the scene. Waterloo was requested to stand by at the Columbia fire station.

The area affected was heavily wooded with multiple sinkholes and very rough terrain, Columbia Assistant Fire Chief Jim Broshears said. One nearby structure was protected from the flames, he said.

Firefighters were released from the scene within a couple of hours.
