A multi-year project set to improve an intersection in Mercer County has entered its final phase. 

As part of the Route 18-Route 58 Improvement Project, the intersection near Thiel College in Greenville Borough will be updated.
Construction is set to resume March 23, 2026, and be completed by July 6, 2026.

The project includes work on Route 18 from the intersection of Route 358 to the intersection with Mill Hill Road, and Route 58 from the intersection with Route 18 to East Craig Street. 

A release states that work will include the final paving, painting roadway markers and lines. The project will also work on landscaping, sidewalk and ADA-compliant curb ramps updates.

The Lindy Paving contract for the project cost $7.9million and is funded predominantly with state and federal funds, according to a news release.

The project officially began in Fall 2024.

PennDOT urges drivers to be cautious in work zones and be alert to changing conditions.

The release also states that traffic pattern shifts, lane restrictions and traffic controlled by flaggers will be present.
