Waterloo firefighters rescued a motorist whose car became disabled after he allegedly drove around street barricades and into a flooded street early Friday. Street department workers called authorities to the stranded driver in the 2700 block of West Ridgeway Avenue near Black Hawk Creek around 2:20 a.m. Friday, and firefighters found the compact passenger car 150 yards out with a swift current lapping at the bottom of the doors. “He got down where the water was really coming over the roadway and his vehicle stalled … He was flashing us with his headlights, so he was in distress,” said Battalion Chief Ben Petersen with Waterloo Fire Rescue. “The water was clipping through there.”
