ST. LOUIS – The Missouri Department of Transportation and its contractor, KCI Construction, have come to an official agreement on repairs needed due to damaged girders on a bridge on Interstate 55 in the city of St. Louis.
Last October, work on the northbound section of Interstate 55 over the Union Pacific Railroad bridge, just south of Loughborough Avenue was delayed due to damage to the girders on the bridge.
As part of the repair, the contractor will replace both the girders and the bearings on the bridge. The contractor is responsible for all costs associated with engineering, design and installation of the girders. The contractor also paid for an additional crossover south of the bridge, so crews could complete the redecking work on the southbound I-55 bridge over the River Des Peres.
Currently, crews have removed the damaged girders from the northbound I-55 bridge and are waiting for the new girders and bearings to be delivered later this fall. Once the girders arrive, they will be installed.
In addition, crews continue working on the southbound I-55 bridge over the River Des Peres and have recently started working on the southbound I-55 bridges over Green Park Road and Gravois Creek.
MoDOT expects the bridge work to be complete in fall 2025 with resurfacing of I-55 to continue into 2026.
“Our priority at this time is to continue to work with the contractor to get the road construction completed and the roadway reopened to traffic,” said Tom Blair, MoDOT St. Louis district engineer.
