    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
