Crews plan to restrict a portion of Route 22 in Monroeville to one lane on Wednesday.
The single-lane restrictions will occur from 9 a.m. to 3 p.m. May 22 between Old William Penn Highway and Haymaker Road.
Workers from Allison Park Contractors will repair a sign located on the Pennsylvania Turnpike overpass.
The work is not part of the $11 million, year-long project that started earlier in May that includes replacing traffic lights, drainage improvements and structure work on the bridge connecting Route 22 to Route 286.
