Bob Skrak, PennDOT's Butler County maintenance supervisor, looks over a section of Old Plank Road in Butler Township on Friday that was undercut by water flowing from a broken Pennsylvania American water line. The pipe shown is not the water line, but a drain that runs under the road. The water main broke near the intersection of Dutchtown Road and Old Plank Road on Thursday afternoon. The damage forced a section of Old Plank Road to be closed. Another section of Old Plank Road, between Litman Road and McQuistion Road, already had been closed because of damage from Wednesday night's storms.
