The Ben Sawyer Bridge is a swing bridge that connects the town of Mount Pleasant with Sullivan's Island in South Carolina. The bridge swings on its central axis to open for boat traffic which is too tall to clear the bridge, and has an operator's house in the center of the swing span from which an tender can operate the bridge. The bridge was originally constructed in 1945, but the steel superstructure for the approach spans and swing span was replaced in 2010, albeit retaining the same general appearance.
