Phase: Construction
Location: Westmoreland County
Anticipated cost: $88.7 million
Finley Road and Indian Hill Road were opened in the new roundabout configuration on November 16, 2026. Drivers are asked to exercise caution and drive at a reduced speed within the roundabout and work zone as Finley Road and Indian Hill Road may have short-term flagging operations as needed. Additionally, eastbound I-70 entrance and exit ramps will remain closed at the Arnold City interchange. Drivers entering eastbound I-70 should detour using Indian Hill Road and Route 201. Drivers exiting eastbound I-70 should detour using Route 201 and Finley Road.
Please also be advised that lane shifts are in place on eastbound and westbound I-70 at Exit 43 (Route 201 Fayette City) and Exit 46 (Route 51) through mid-December 2026. During this time, crews will remove the existing permanent median barriers, place subbase and temporary asphalt, and implement a traffic pattern shift for the next phase of construction.
During the next phase of the project, crews will remove the I-70 median barrier and shift traffic lanes north to rebuild the eastbound travel lane and shoulder.
Highlights of the 2026 construction include:
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
