Long Significance Description:
The C&O Canal is a flat water canal, chartered in 1825. Construction began in 1828 and by 1850 the canal was opened to its terminus at Cumberland, Maryland. The canal ceased operations in 1924 due to flood damage and the buying out of the company by the Baltimore & Ohio Railroad. In 1938, the B&O Railroad sold the canal property to the US government for $2 million dollars. The entire 184.5 miles of the canal was recognized as a National Historic Monument in 1961, and then in 1971 became known as the Chesapeake & Ohio Canal National Historical Park. Under the 1966 National Historic Preservation Act, the Canal was added to the National Register of Historic Places, having historical significance merits under architecture, engineering, commerce, transportation, military history and conservation. A confirmation National Register was approved by the Keeper for the CHOH on August 9, 1979.

The purpose of the C&O Canal was to bring freight and produce from Cumberland, Maryland, to Georgetown. The canal is an excellent example of 19th c. canal building technology. The magnitude of the engineering achievement is exemplified by the 184.5 mile length of the canal, which includes 74 lift locks rising 605 feet. 11 stone aqueducts were constructed to carry the canal prism over large Potomac River tributaries and 241 historic culverts were built to carry smaller streams and roads under the canal. 7 supporting dams were also constructed. Among the noteworthy engineered works on the canal is the Paw Paw Tunnel, which was drilled through 3, 117 feet of bedrock.

Long Physical Description:
The Spillway/Footbridge - Foxhall Road is located on the towpath, directly across from the Foxhall/Canal Road intersection. The towpath was depressed to the top of the six-foot water level of the canal prism, allowing excess water to spill directly into the river. A wooden bridge allowed pedestrians to cross dry shod, while the mules genearally walked thruough the water. The spillway has been concreted over to halt erosion and the current bridge is a non-historic replacement.
