In 1830, merchants from Alexandria (which at the time was within the jurisdiction of the federal District of Columbia) proposed linking their city to Georgetown to capitalize on the new Chesapeake and Ohio Canal (C&O Canal). Congress granted a charter to the Alexandria Canal Company in 1830.
Construction began soon afterwards on the Aqueduct Bridge, which would enable canal boats from the C&O Canal to cross the Potomac River without first unloading at Georgetown. The boats would then continue their trips downstream on a canal on the southwest side of the Potomac until they reached Alexandria's seaport.
Construction of the bridge and of the Alexandria Canal began in 1833. Both were completed a decade later.
The canal ran southwards for seven miles through today's Arlington County and City of Alexandria, Virginia, dropping 38 feet through a series of four locks between Washington Street and the Potomac River in the northern portion of Alexandria. The Canal ended at a Tidal Basin (Pool No. 1) and a Tidal Lock (Lift Lock No. 1) located at the north end of Old Town Alexandria.
The canal was abandoned in 1886. Ten years after the canal closed, an electric trolley line was constructed in 1896 in Arlington on the bed of the towpath that traveled along the canal's west side. Arlington's S. Eads Street now approximates the canal's route in this area.
The Pennsylvania Railroad constructed a branch line to Rosslyn near and along the portion of the canal's route that passed through the area that lies between Arlington National Cemetery and the Potomac River. An open section of Metrorail's Blue Line now travels this route.
After the Key Bridge was completed in 1923, the old superstructure of the Aqueduct Bridge was removed. During the 1980s, Alexandria City archaeologists and the developer of the neighboring Trans-Potomac Canal Center excavated and restored the Tidal Basin and Lock. Aside from these two features, the abutments of the Aqueduct Bridge in Georgetown and Rosslyn, and a pier of the bridge in the Potomac River upstream of the Key Bridge, all of the canal's remnants have either been removed or remain underground.
