Description

This project constructed a new 5.7-mile, eight-lane section of Interstate from west of NC 115 (Old Statesville Rd.) to west of I-85 north of Charlotte. This is the last segment of the I-485 Outer Loop around Charlotte, linking I-77 to I-85. The project also included interchange improvements, service road realignment, and bridge construction. Related but separate projects in the completion of the I-485 Outer Loop include the widening of seven miles of I-85 from four to eight lanes, widening the southern section of I-485 from four to six lanes between I-77 and Rea Road, and the upgrade of the interchange between I-485 and I-85.
