2025 Finley Road Detour Underway July 14                                                               

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.

Detours:

Detour Duration: July 14, 2025 – Early Spring 2026

Closure Purpose: Construct the interchange roundabout and retaining wall between the interchange and railroad.

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.


More details about anticipated construction phasing are included below.

Project Overview

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:

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
