The study corridor begins west of the U.S. 74/76 interchange with U.S. 701 in Whiteville and continues along existing U.S. 74/76 to 1.25 miles west of Bolton. It proceeds southward on a new location to the Columbus-Brunswick county line. The study corridor travels southward alongside existing N.C. 211 from the county line to U.S. 17 in Supply. The I-74 corridor then turns southwest and travels along the U.S. 17 corridor, utilizing the Shallotte Bypass, and finally ending at the South Carolina state line. The total length of the project varies from 63.3 miles to 65.5 miles, depending on which alignments are selected.
