Goose Island (District of Columbia)

Oxon Creek is a stream on the Potomac River which feeds a cove that straddles the border between Washington, D.C. and Prince George's County, Maryland just north of Interstate 495 (Capital Beltway) at Woodrow Wilson Bridge. Oxon Creek heads at the confluence of Oxon Run and Barnaby Run, sometimes referred to as Winkle Doodle Run. It starts just inside the boundary of D.C. and then runs 1.5 miles (2.4 km) to the south and west into Maryland to empty into the Potomac at Goose Island (a sand bar often under water) across from the city of Alexandria, Virginia. Before reaching the Potomac, the creek widens to form Oxon Cove which is partially in Maryland and partially in Washington, D.C.. The creek is almost entirely within Oxon Cove National Park, except for the first few feet in D.C. and a portion of the cove on the southside of the Blue Plains Advanced Wastewater Treatment Plant.Two bridges cross the creek. The Anacostia Freeway crosses it on a bridge where it becomes a tidal stream and the Oxon Hill Farm Trail crosses it where it is still narrow. The unusual spelling is either historical or a reference to Oxfordshire, England, though it was usually labelled as Oxen Creek on maps prior to 1898. The distinction between Oxon Creek and Oxon Run is often not recognized and so both are frequently referred to as Oxon Run. USGS first started labeling it as Oxon Creek in 1892.

The Alexandria Canal was a canal in the United States that connected the city of Alexandria to Georgetown in the District of Columbia. 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 in 1833 and was completed in 1843. The Aqueduct Bridge (also begun in 1833 and completed in 1843) enabled canal boats from the C&O Canal to cross the Potomac River without descending to the river level. The boats would then continue their trips downstream on a canal on the southwest side of the Potomac until they reached Alexandria's seaport. 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 near and along the canal's west side (see: Washington-Mount Vernon line of the Washington, Alexandria, and Mount Vernon Electric Railway). Arlington's South Eads Street now approximates the canal's route in this area.Also in 1896, the Washington Southern Railway opened a line that traveled between the southern end of the Long Bridge and the southern end of the Aqueduct Bridge. The line, which passed the present site of The Pentagon, traveled within the grade of the former canal in the area that lies between Arlington National Cemetery and the Potomac River. The line became in 1904 the Rosslyn Connecting Railroad, which the Pennsylvania Railroad owned through a subsidiary, the Philadelphia, Baltimore and Washington Railroad (PB&W).The Rosslyn Connecting Railroad abandoned nearly all of its line in 1962 and closed in 1969. The Washington Metropolitan Area Transit Authority then constructed an open section of Metrorail's Blue Line along a portion of the railroad's route that had traveled within the canal's grade. The section of the Blue Line opened on July 1, 1977.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 the Tidal Basin and Lock and covered the original remnants with a reconstruction. 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.
