US 501 is a north–south United States highway that traverses the majority of North Carolina in concurrency with US 15, known as "15-501" ("Fifteen Five-o-one"). It enters North Carolina at the South Carolina state line with an intersection of Interstate 95 (I-95) while overlapping US 301, near South of the Border. It goes northwest through Rowland where the overlap with US 301 terminates, and then travels through Raemon to Laurinburg.  Once at Laurinburg, it overlaps briefly with I-74/US 74 before connecting with US 15.  The majority of the route, to this point, is a two-lane rural road.Merging with US 15, it becomes what is known by local residents as "15-501" ("Fifteen Five-o-one"), a concurrency that extends for 106 miles (171 km) across central North Carolina. After Laurinburg it goes north to Aberdeen, linking briefly with US 1 before continuing to Pinehurst.  In Pinehurst, 15-501 goes through a roundabout then continues north through Carthage, then back to US 1.  After traveling through Sanford on another brief concurrency with US 1, it exits off the freeway and goes due north to Pittsboro.  After Pittsboro, 15-501 goes through Chapel Hill and then into Durham. NCDOT has been trying to remedy traffic problems by making the route a superstreet for better traffic flow.  In Durham, 15-501 upgrades to an urban freeway, allowing for quick access to Interstate 85, and from south Durham to north; the freeway ends merging into I-85.  At exit 176B on I-85, US 501 splits off towards Roxboro, while US 15 continues with I-85 towards Oxford.After Durham, US 501 goes north to Roxboro, then into South Boston, Virginia after crossing the state line; the majority of this section is a four-lane expressway.
