In [[South Carolina]], US&nbsp;1 generally serves mostly rural areas as it falls west of [[Interstate 95|I-95]] while the coastal areas are served by routes east of it. Starting in South Carolina, US&nbsp;1 is paralleled by [[Interstate 20|I-20]] along the [[Atlantic Seaboard Fall Line]] through [[Aiken, South Carolina|Aiken]], [[Lexington, South Carolina|Lexington]], and [[Columbia, South Carolina|Columbia]] to [[Camden, South Carolina|Camden]] and [[Lugoff, South Carolina|Lugoff]]. US&nbsp;1 functions as a local two-lane road with occasional boulevard stretches. After Camden, US&nbsp;1 continues northeast away from any Interstate toward [[Bethune, South Carolina|Bethune]], [[Patrick, South Carolina|Patrick]], [[McBee, South Carolina|McBee]], and [[Cheraw, South Carolina|Cheraw]] with no bypasses or four-lane sections except around Cheraw through the [[U.S. Route 52|US&nbsp;52]] and [[South Carolina Highway 9]] (SC&nbsp;9) concurrencies. After SC&nbsp;9, it continues northward into North Carolina as a two -lane highway. The [[South Carolina Department of Transportation]] (SCDOT) has no plans to widen or bypass any US&nbsp;1 alignments northeast of Camden to the North Carolina line.

Between the South Carolina line and the [[U.S. Route 74|US&nbsp;74]] bypass, US&nbsp;1 is a two-lane road but sees a considerable amount of truck and tourist traffic of people cutting through from the US&nbsp;74/[[U.S. Route 220|US&nbsp;220]] and [[Interstate 73|I-73]]/[[Interstate 74|I-74]] corridor attempting to reach points south and east. US&nbsp;1 goes through downtown [[Rockingham, North Carolina|Rockingham]], with a bypass in the future plans. North of the [[North Carolina Highway 177]] (NC&nbsp;177) junction, it becomes four lanes or greater, becoming a [[superstreet]] with limited access and then becoming a limited access freeway. US&nbsp;1 becomes a major artery for the state as it moves north of Rockingham. After [[Richmond County, North Carolina|Richmond County]], it goes into [[Moore County, North Carolina|Moore County]] with two expressway bypasses in [[Southern Pines, North Carolina|Southern Pines]], [[Vass, North Carolina|Vass]], and [[Cameron, North Carolina|Cameron]]. US&nbsp;1 continues with the [[Jefferson Davis Highway]] label through [[Lee County, North Carolina|Lee County]] and [[Sanford, North Carolina|Sanford]], and on to [[Cary, North Carolina|Cary]] and [[Raleigh, North Carolina|Raleigh]]. US&nbsp;1 runs concurrently with [[U.S. Route 64|US&nbsp;64]] through most of Cary, where the freeway recently underwent a major renovation and improvements that added lanes in both directions.<ref>{{cite web |title=US 1/64 Widening |url = http://www.townofcary.org/Departments/Engineering/Engineering_Projects/US_1_64_Widening.htm |publisher=Town of Cary, North Carolina |archive-url = https://web.archive.org/web/20120314183019/http://www.townofcary.org/Departments/Engineering/Engineering_Projects/US_1_64_Widening.htm |archive-date = March 14, 2012 }}{{full citation needed|date=January 2017}}</ref> North of Raleigh, US&nbsp;1 (known as Capital Boulevard in northern Wake County) crosses [[Interstate 540 (North Carolina)|I-540]] and then again becomes a four-lane divided arterial to [[Interstate 85|I-85]] near [[Henderson, North Carolina|Henderson]]. The [[North Carolina Department of Transportation]] (NCDOT) has begun a corridor study for this section of US&nbsp;1.<ref>{{cite web |url = http://www.ncdot.org/projects/US1corridor/ |title = US&nbsp;1 Corridor Study |publisher = North Carolina Department of Transportation |access-date = August 9, 2012 |archive-date = March 24, 2012 |archive-url = https://web.archive.org/web/20120324052923/http://www.ncdot.org/projects/US1corridor/ |url-status = dead }}</ref> Moreover, NCDOT is planning to finish four-laning US&nbsp;1 in Richmond County past NC&nbsp;177 with a Rockingham bypass to the east. There are no plans from SCDOT to widen US&nbsp;1 from the state line. From Henderson into Virginia, US&nbsp;1 runs parallel with I-85 as a two-lane local road until the state line, where Virginia hosts a continuous third center lane for alternate passing toward [[U.S. Route 58|US&nbsp;58]] before [[South Hill, Virginia|South Hill]].
