US 1 followed the Atlantic Seaboard Fall Line west of the coastal plain, I-95 takes a more direct route through the plain and its swamps. Although some of this part of US 1 was followed by other Interstates—I-85 between Petersburg and Henderson, North Carolina, and I-20 between Camden, South Carolina, and Augusta, Georgia—the rest remains an independent route with four lanes in many places. By the late 1970s, most of I-95 had been completed, replacing US 1 as the main corridor of the east coast and relegating most of it to local road status.
