U.S. Route 1 (US 1) is a north–south United States highway that traverses along through the South Carolina sandhills region; it connects the cities of North Augusta, Aiken, Lexington, Columbia, Camden, and Cheraw.
US 1 enters South Carolina in North Augusta. From North Augusta to Aiken, US 1 is a divided four-lane highway. It goes through the historic district of Aiken, heading north through Batesburg-Leesville, Lexington, into Columbia up to Camden. US 1 parallels I-20, crossing it three times until it branches northeast at Camden. It also has junctions with I-26 and I-77 in Columbia. In Richland County, it goes through downtown Columbia along Gervais Street, passing directly in front of the State Capitol building; connecting via Millwood Avenue, it continues northeast along Two Notch Road, named for when the road was marked by posts with two notches carved. From Camden, it continues northeast as a two-lane road to the town of Cheraw and Cheraw State Park before entering the state of North Carolina.
