Work is scheduled to begin this week on Main Street in Slippery Rock.
PennDOT officials say crews will be resurfacing the road beginning at the intersection with West Liberty Street through the New Castle Street intersection.
After that portion of the project is complete, crews will be resurfacing Grove City Road (Route 173) from Franklin Street up to the Mercer County line.
The project is expected to be completed by this September. The estimated cost is around $4.1 million.
