Concrete falls on ramp to Lake Shore Drive, snarling evening rush traffic

Updated: September 3, 2013 10:00PM



A piece of concrete fell from an overpass onto a ramp to Lake Shore Drive during the Tuesday evening commute, snarling traffic in the area.

The piece of concrete separated from an underpass about 4:30 p.m. and landed on the LaSalle Drive ramp to Lake Shore Drive, Chicago Department of Transportation spokesman Pete Scales said.

No one was hurt, and no property was damaged, Scales said.

The piece of concrete that fell measured 3 feet by 10 feet and was about an inch or two thick, Scales said. It serves as a skim coating underneath the bridge to protect the steel structure inside.

The bridge dates back to the 1930s. It last underwent “significant” repairs about five years ago, Scales said. Officials deemed the bridge in fair condition when it was last inspected, sometime within the past two years.

Crews were working on the bridge Tuesday evening to remove any other possible loose concrete, and they hoped to reopen traffic in the area by 8 p.m., Scales said. Lake Shore Drive itself remains open to traffic.

Water damage or vibrations from passing vehicles could have caused the piece to separate from the underpass, he said.
