U.S. Route 278 (US 278) is an east–west United States highway that traverses through the South Carolina Lowcountry, from North Augusta to Hilton Head Island.
After crossing the Savannah River from Georgia, US 278 bypasses downtown North Augusta, South Carolina to the south en route to Beech Island and Johnson Crossroads. It then forms a de facto northern boundary of the Savannah River Site, crossing into the property on a few occasions. The route then continues eastward and then southward through the communities of Barnwell, Kline, Allendale, Fairfax, Hampton, Varnville, Ridgeland, and Hardeeville where it meets I-95. US 278 shares the route between Ridgeland and Hardeeville with US 17.
