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.
Motorists should exercise caution traveling through work zones and be alert for workers. Safety is everyone’s responsibility.
