A concrete company caught fire near I-94 in Racine County Friday morning.  Firefighters called in at least 4 alarms for the fire at the Zignego Concrete Company near Highway 11 and I-94.

Authorities say it appears everyone got our of the building okay.  A witness tells Newsradio 620 WTMJ that he heard a truck may have started on fire and that the fire spread.

Witness Tim Peterson says they actually heard the fire first.  They heard loud booms, which they think may have been tires popping on the trucks.

Smoke from the fire was visible from I-94.
