Prepare For Traffic Delays On Interstate 79

July 7, 2026 3:41 pm

PennDOT announced on Tuesday that there will be nightly ramp closures on Interstate 79 at Exit 14, Masontown/Waynesburg, in Franklin Township in Greene County. They say the ramp closures will occur nightly from 8:00 p.m. until 6:00 a.m. beginning Monday, July 13th, and continue through Saturday, July 25th.   All work depends on weather and operations.  Officials say the ramp closures will be coordinated so detour routes do not conflict with one another.  Current I-79 single-lane restrictions between Exit 14, Masontown/Waynesburg, and Exit 23, Marianna/Prosperity,  that began on June 18th, will continue until late August.  The ramp closures will allow crews to perform concrete patching and to overlay entrance and exit ramps with asphalt.  The 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, a $45.9 million infrastructure investment.
