According to John Boyanoski's book, The Ghosts of Upstate South Carolina, the Tyger River Bridge is supposedly haunted. Known locally as "Crybaby Bridge", the area is purported to be haunted by the ghost of a woman who tossed an unwanted baby from the bridge. No historical record corroborates the incident.
Wikipedia states that the "Crybaby Bridge" tale is a common legend, and that similar stories can be found for other bridges in the United States.
