    Additional Interstate 70 Traffic Impacts Scheduled in Westmoreland County

    September 30, 2026

    Due to the Arnold City Interchange Project.

    Uniontown, PA—Pennsylvania Department of Transportation (PennDOT) District 12 is announcing additional traffic impacts on Interstate 70 between Exit 43 (Route 201 Fayette City) and Exit 46 (Route 51/I-70 Interchange), in Rostraver Township, Westmoreland County.

    Additional Traffic Impacts:

    Monday, October 5 through Saturday, October 10

    • Single-lane restrictions in both directions of I-70 from 6:00 PM to 6:00 AM

    Ongoing Traffic Impacts:

    Monday, September 28 through Friday, October 2

    • Single-lane restrictions in both directions of I-70 from 6:00 PM to 6:00 AM

    Monday, September 28 through mid-December

    • Drivers will encounter a lane shift in both directions of I-70 at the start and end of the project limits.

    The current lane shift near Crawford Lane Bridge will be eliminated.

    During this time, crews will remove existing permanent median barriers, place subbase and temporary asphalt and implement a traffic pattern shift.

    Drivers are asked to exercise caution driving through the work zone. Safety is everyone’s responsibility.

    This work is part of the I-70 at Arnold City Interchange project, which connects Route 3011 (Finley Road/Indian Hill Road) and Daugherty Lane to I-70. The project aims to enhance safety and traffic operations at the interchange and along the interstate. 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. Golden Triangle Construction Company, Inc., is the prime contractor.

    The $89 million infrastructure investment will include widening the median from four (4) feet to 10 feet and the outside shoulders from 10 to 12 feet. The reconstructed interchange will utilize a diamond configuration with a five-leg roundabout connecting the eastbound ramps with Indian Hill Road and Finley Road. The westbound ramps will be rebuilt as standard diamond ramps with a non-signalized intersection. The roadway will be shifted approximately four (4) feet to the north to accommodate the widening.
