Beginning on Monday, July 14 and remaining through early spring 2026, closures will be in place at the eastbound ramps of the Arnold City Interchange (Exit 44). Traffic will be redirected to the I-70/Route 201 Interchange (westbound) or I-70/Route 51 Interchange (eastbound). All work depends on weather and operations.

Construction began in April 2025 and is expected to continue through 2028. Eastbound ramps and Finley Road will close at the interchange for approximately five months in 2025 to build a mechanically stabilized earth (MSE) wall and roundabout. Detours will follow I-70 to the Route 201 and Route 51 interchanges. While Finley Road is raised, a temporary driveway will be in place east of the interchange to provide access for homes and properties for about one month.
This project connects Route 3011, Finley Road, Indian Hill Road, and Daugherty Lane to I-70, and improve safety and traffic operations at the interchange and along I-70. The existing Exit 43 interchange (Donora - Fayette City) will be renamed Donora – Rostraver Road, and the existing Exit 44 interchange (Arnold City) will be renamed Fayette City - Finley Road. The project area is approximately 1.75 miles long, from the I-70 bridge over the Wheeling and Lake Erie Railroad to 1.37 miles east of the Arnold City Interchange in Rostraver Township. Planned construction through 2028 will include:
Arnold City Interchange Improvements
Indian Hill Road Bridge over I-70
Crawford Lane Bridge over I-70
