Repairs to the John Harris Memorial Bridge that spans the Susquehanna River near Harrisburg could lead to traffic delays on I-83 over the next few weekends.

Extension dam repairs will impact southbound traffic Friday through Monday and the weekends of Aug. 26-29 and Sept. 16-19, according to the Pennsylvania Department of Transportation.

PennDOT spokesperson Dave Thompson said extensions dams are the mechanisms that allow bridges to expand and contract with temperature changes. These mechanisms, common to most bridges, require regular maintenance, he said.
