Repairs to the buckled Kennedy Expressway cost more than $70,000, but the construction company doing work in the tunnel below the area won't be held responsible, officials said Tuesday.
Workers from Lorig Construction were installing concrete in a freight tunnel underneath the northbound Kennedy around Adams when some of that mixture flowed up through a crack in the wall, causing the buckle.
The contractor was using an approved mixture and followed specifications, the Illinois Department of Transportation said, according to the Chicago Tribune.
"We don't see the contractor at this time liable for the cost. They followed what IDOT said should be done, project engineer Jacek Tyszkiewicz told the newspaper.
Crews worked through the night Wednesday to repair the construction nightmare and all lanes were reopened by the Thursday morning rush.
