I-70 at Arnold City Interchange

Design Underway

The Arnold City Interchange Improvements Project, connecting Route 3011, Finley Road, Indian Hill Road, and Daugherty Lane to I-70, 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.
