Construction on a Spring Grove bridge led to a brush fire that threatened three homes, and a smaller fire burned in Crystal Lake about an hour later.

At 2:33 p.m., the Spring Grove Fire Protection District was called to the area of Winn and Main/East Solon roads, where construction workers had been cutting a pipe for a bridge. A spark ignited dry grass and winds fanned the flames, pushing the fire to the north and west. It traveled over a berm toward the Whitetail Crossing subdivision and a farm, Chief Rich Tobiasz said.

The fire consumed about 15 acres and approached three homes. It started to circle around one of them, but brick landscaping prevented the house from catching fire, Tobiasz said.
