2025 Construction Overview

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. Click the links below to learn more about the anticipated construction activities in 2025.

Project Overview

This project will connect 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, named Donora - Fayette City, will be renamed Donora – Rostraver Road, and the existing Exit 44 interchange, named Arnold City, will be renamed Fayette City - Finley Road. The project area is approximately 1.75 miles long, extending 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 phasing will include:

I-70 Mainline Reconstruction

  • Full depth pavement replacement
  • Drainage improvements
  • Stormwater management
  • Replacement of overpass structures
  • Grade improvements to provide adequate clearance

Arnold City Interchange Improvements

  • Interchange geometry will be improved to provide adequate ramp lengths for traffic to safely exit from and merge onto I-70
  • The grades on the ramps will be reduced to meet current standards
  • A roundabout will combine the eastbound ramps/Indian Hill Road intersection and the Indian Hill/Finley Road intersections

Indian Hill Road Bridge over I-70

  • Replaced to provide adequate width and vertical clearance (16’ 6” minimum) for I-70

Crawford Lane Bridge over I-70

  • Replaced to provide adequate width and vertical clearance (16’ 6” minimum) for I-70
  • Location shifted to east to allow new bridge to be constructed while existing bridge remains in use

    An informational project brochure is available to view online or download and print to share project information with the community.

    Public Involvement

    PennDOT held an Open House Public Meeting and Public Officials Briefing in November 2017, a virtual public meeting in November 2021, and an Open House Public Meeting in October 2023 and April 2025. At each of these meetings, the Department made a short presentation to provide an overview of the project, purpose and needs, environmental features, studies performed, design work completed to date, and next steps.
