Phase: Construction
Location: Westmoreland County
Anticipated cost: $88.7 million
Traffic impacts are planned to occur on I-70 between Exit 43 (Route 201 Fayette City) and Exit 46 (Route 51/I-70 Interchange) on:
During this time, crews will be completing temporary widening work and removing the existing temporary access road just west of Crawford Lane bridge and placing a temporary covering over a permanent inlet. In addition, crews will be placing temporary concrete pavement for the westbound temporary widening.
Construction is underway and the following activities are expected to take place:
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.
As construction continues, track construction progress with updated construction photos.
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
