Thousands of commuters were stopped cold on Lake Shore Drive Tuesday evening as a mile-long backup formed from North Avenue Beach South to Soldier Field.
The exit and entrance ramps from and onto Lake Shore Drive at LaSalle/North Avenue were shut down because of concrete chunks giving way from the overpass and into LaSalle Drive below.
No vehicles were hit and no one was injured as the concrete fell and drivers called it into 911 just before 4 p.m. Tuesday.
“This was lucky,” said a Chicago Police Department Sergeant on the scene. “It must have fallen during a red light when there’s no one under the Drive,” he observed.
Chicago Department of Transportation crews were on the scene cleaning up the rubble. Another inspection crew is expected to look at the area from where the concrete fell.
According to police, a chunk of concrete is still hanging from above.
CDOT says that these overpasses are inspected every two years. This particular one was built in the 1930s last repaired 5 years ago and has a rating of “fair.”
The exit ramp reopened around 8:30 p.m.
