    Interstate 79 Waynesburg to Marianna Preservation Project Begins in Greene and Washington counties

    June 18, 2026

    Lane restrictions are in place on Interstate 79.

    Uniontown, PA - Pennsylvania Department of Transportation (PennDOT) District 12 is announcing that single-lane restrictions are in place in both directions of Interstate 79 between Exit 14 (Masontown/Waynesburg) and Exit 23 (Marianna/Prosperity) in Greene and Washington counties. All work depends on weather and operations.

    Single-lane restrictions will be in place until late August.

    Crews from Lindy Paving will perform patch and asphalt overlay of concrete pavement sections, mill and resurface asphalt pavement, minor drainage improvements, guiderail updates, replacement of signage, pavement markings and delineation, and relocation of Intelligent Transportation System equipment.

    This work is part of the I-79 Waynesburg to Marianna Project, which will make improvements to approximately 11 miles of I-79, extending through Franklin and Washington townships in Greene County and Amwell Township in Washington County. Lindy Paving, Inc., is the prime contractor.

    This $45.9 million infrastructure investment includes preservation work on 14 structures and pavement rehabilitation along the corridor. The proposed work consists of an 8-mile asphalt overlay of existing concrete pavement sections and a 4-inch mill and fill on the existing asphalt sections to enhance ride quality, extend pavement life, and ensure continued safe and efficient travel.

    Drivers are asked to exercise caution driving through the work zone. Safety is everyone’s responsibility.
