The Broad River Bridge is a 1.7-mile (2.7 km) long highway bridge that spans the Broad River in Beaufort County, South Carolina. Originally built as a two-lane drawbridge, growth pressures and safety concerns demanded that a larger and taller fixed-span bridge be built. The current four-lane wide structure was completed in 2004 and carries South Carolina Highway 170 as it connects northern and southern sections of Beaufort County. Portions of the previous bridge were purchased by Beaufort County and are now used as a fishing dock.
