Nighttime Work Planned for Route 18 in Greenville, Mercer County
Oil City, PA – As part of the contract for work on the Route 18-Route 58 Improvement Project, paving will be done on Route 18 from Route 846 (Orangeville Road) to the Shenango River bridge in Greenville Borough, Mercer County.
Work is expected to be done during the overnight hours, approximately 7:00 PM to 7:00 AM, starting September 22 and take about five days to complete. Drivers should be alert for lane restrictions and traffic controlled by flaggers.
Earlier work along that same stretch of roadway included updated drainage, sidewalk repairs, and ADA curb ramps.
Drivers are also reminded that starting September 30, 2025, Route 58 will be closed to westbound traffic between the intersection with Packard Avenue Extension and the intersection with Ridgeway Avenue. The detour is expected to remain in place until October 7, 2025.
The detour for cars will be posted using Route 18 to Williamson Road to Route 58. The truck detour will be posted using Route 18 to Route 322 to Route 58.
