The Missouri Department of Transportation (MoDOT) and contractor KCI Construction have reached an agreement to repair 80 girders on a bridge that was damaged during a rehabilitation project on Interstate 55. KCI Construction will replace the girders and bearings on one of the 13 bridges being rehabilitated between Lindbergh and Interstate 44 in St. Louis. The bridge was damaged when a demolition subcontractor used a breaker hammer, causing significant damage to the girders. KCI Construction will be responsible for all costs associated with the repair work. The repair is estimated to cost at least $10 million, and MoDOT expects the bridge work to be completed in fall 2025. [Extracted from the article]

A $63 million improvement project along Interstate 55 in Missouri has been delayed and will require an additional $10 million to repair a bridge that was damaged by a demolition subcontractor.
