The I-485 project is the latest of many collaborations between Blythe and the WSP design firm. The complete work site stretches 18.2 miles along the existing I-485, from Westinghouse Blvd to around Independence Blvd. The main objective of the project is to create high-occupancy toll (HOT) lanes along that entire stretch or roadway. In addition, crews will install 17 structures, 15.3 miles of new sound wall, and a new center median access at Johnston Rd.
The proposed express lanes on I-485 would connect with proposed express lanes on nearby U.S. 74 (Independence Boulevard), resulting in a seamless network of express lanes in southern Mecklenburg County that would improve traffic flow and provide reliable travel times.
