Harbor Island is a small residential barrier island located 14 miles (22 km) east of Beaufort, South Carolina. It is one of the Carolina Sea Islands. Most of the island is tidal marsh, though approximately 800 acres (3.2 km2) of upland acreage exists on the northeastern portions. The residential portion of the island was listed as a census-designated place in the 2020 census, with a population of 209.[5]
Harbor Island is served by U.S. Route 21 (US 21), the only vehicular access route to the island and other nearby islands. The original US 21 Harbor River Bridge, a swing-span bridge built in 1939, was narrow and structurally deficient and was replaced with a modern fixed-span bridge to ensure safer and reliable access. The new bridge opened to traffic on April 25, 2021.[6][7]
