Notes
  • Significance: The Chesapeake and Ohio Canal Lift Bridge is significant as a rare surviving example of a short-span railroad vertical lift bridge, for its unusual design elements to allow unimpeded passage of canal boats pulled by animals treading the canal's towpath, and for the economy of its design. It is the only such structure built across the Chesapeake and Ohio Canal.
