I-70 at Arnold City Interchange

Design Underway

The Arnold City Interchange Improvements Project, located in Rostraver Township, is intended to improve safety and traffic operations at the interchange and along I-70. 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. On mainline I-70, the project will include widening the median from 4 feet to 10 feet and widening the outside shoulders from 10 to 12 feet. The reconstructed interchange will utilize a diamond configuration with a five-leg roundabout that will connect the eastbound ramps with Indian Hill Road and Finley Road. The westbound ramps will be reconstructed as standard diamond ramps with an unsignalized intersection The roadway will be shifted approximately 4 feet to the north. View the Arnold City Typical Section for the proposed typical section of the I-70 mainline. Two bridges will also be replaced: the Indian Hill Road and Crawford Lane bridges over I-70. Both bridges will be replaced east of and adjacent to their existing location.

Sign-in sheets indicate that sixty (60) citizens attended the Open House Public Meeting and six (6) officials attended the Public Officials Briefing. The public and public officials were encouraged to visit information stations on the project design and environmental constraints. PennDOT The Department made a short presentation at both meetings to provide an overview of the project, purpose and needs, environmental features, studies performed, Alternatives 1A and 2A, and next steps.
