Oxon Creek

Goose Island is a vanishing island located in the Potomac River in the southwest quadrant of Washington, D.C., in the United States. It is a rarely above-water mudflat located at the mouth of Oxon Creek, roughly between Oronoco Bay in Alexandria and Marbury Point (Shepherds Landing), now part of the Blue Plains water treatment plant. National Oceanic and Atmospheric Administration nautical charts indicate that Goose Island sits within a shallow area, extending south past the Woodrow Wilson Bridge into Maryland, that is used to deposit dredging spoils.

Blue Plains is a locale in the southwest quadrant of Washington, D.C. The area gives its name to the Blue Plains Advanced Wastewater Treatment Plant.

Oxon Cove Park and Oxon Cove Farm is a national historic district that includes a living farm museum operated by the National Park Service, and located at Oxon Hill, Prince George's County, Maryland. It is part of National Capital Parks-East. It was listed on the National Register of Historic Places in 2003.The park provides an excellent resource for environmental studies, wildlife observing, fishing, and other recreational activities made possible by easy access to the Potomac River. Fourteen buildings and two structures are located in the historic district and associated with the property's sequential development as a plantation, an institutional agricultural complex, and a farm museum.

Blue Plains Advanced Wastewater Treatment Plant, located at 5000 Overlook Ave SW, Washington, DC 20032, is the largest advanced wastewater treatment plant in the world. The facility is operated by the District of Columbia Water and Sewer Authority (DC Water). The plant opened in 1937 as a primary treatment facility, and advanced treatment capacity was added in the 1970s and 1980s. The effluent that leaves Blue Plains is discharged to the Potomac River and meets some of the most stringent permit limits in the United States.

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.

U.S. Naval Torpedo Station, Alexandria was a facility of the United States Navy, located in Alexandria, Virginia, that existed from 1918 to 1945. After its closure, it was redeveloped into the Torpedo Factory Art Center.

The Alexandria Archaeology Museum is an institution dedicated to the preservation and study of the archaeological heritage of Alexandria, Virginia.According to the National Park Service, the museum exhibits feature's 10,000 years of the human history of Alexandria.In addition to artifacts, the museum also jointly holds a collection of 160 oral histories in conjunction with two other institutions, the Black History Mureum and the Lyceum.

The United States Naval Research Laboratory (NRL) is the corporate research laboratory for the United States Navy and the United States Marine Corps. It was founded in 1923 and conducts basic scientific research, applied research, technological development and prototyping. The laboratory's specialties include plasma physics, space physics, materials science, and tactical electronic warfare. NRL is one of the first US government scientific R&D laboratories, having opened in 1923 at the instigation of Thomas Edison, and is currently under the Office of Naval Research.As of 2016, NRL was a Navy Working Capital Fund activity, which means it is not a line-item in the US Federal Budget. Instead of direct funding from Congress, all costs, including overhead, were recovered through sponsor-funded research projects. NRL's research expenditures were approximately $1 billion per year.

The Torpedo Factory Art Center is the former U.S. Naval Torpedo Station, a naval munitions factory on the banks of the Potomac River in Old Town, Alexandria, Virginia which was converted into an art center in 1974. The facility is located at 105 N. Union Street, near the eastern end of King Street.The Torpedo Factory Art Center is home to the largest number of publicly accessible working artist studios in the U.S. Each year, more than a half-million visitors interact with its community of artists. As of March 2022, it housed 82 artists' studios, 8 galleries, and workshops, with some 165 professional visual artists who work in a variety of media, including painting, ceramics, photography, jewelry, stained glass, fiber, printmaking, and sculpture. The Torpedo Factory has become a model of creative placemaking for other communities.Artists are selected as part of an annual jury and re-jury process. Once accepted, they receive a three-year lease of publicly subsidized rent.

The Woodrow Wilson Memorial Bridge (also known as the Woodrow Wilson Bridge or the Wilson Bridge) is a bascule bridge that spans the Potomac River between the independent city of Alexandria, Virginia, and Oxon Hill in Prince George's County, Maryland, United States. The original bridge was one of only a handful of drawbridges in the U.S. Interstate Highway System. It contained the only portion of the Interstate system owned and operated by the federal government until construction was completed and it was turned over to the Virginia and Maryland departments of transportation.The Wilson Bridge carries Interstate 95 (I-95) and I-495 (the Capital Beltway). The drawbridge on the original span opened about 260 times a year, frequently disrupting traffic on a bridge that carried about 250,000 cars each day. The new, higher span requires fewer openings. The bridge's west abutment is in Virginia, a small portion is in Washington, D.C., and the remaining majority of it is within Maryland (because that section of the Potomac River is within Maryland's borders). About 300 feet (91 m) of the western mid-span portion of the bridge crosses the tip of the southernmost corner of the District of Columbia. It is the only bridge in the United States that crosses the borders of three state-level jurisdictions (DC, Maryland, and Virginia). The section in Washington, D.C., is also the shortest segment of Interstate highway between state lines.The bridge is named for the 28th President of the United States, Woodrow Wilson (1856–1924), a native of Staunton, Virginia. While he was president, Wilson reportedly spent an average of two hours a day riding in his automobile to relax or to "loosen his mind from the problems before him." President Wilson was an advocate of automobile and highway improvements in the United States. In 1916, he said, "My interest in good roads is...to bind communities together and open their intercourse, so that it will flow with absolute freedom and facility".

Robinson Terminal Warehouse LLC is a warehouse and logistics company based in Springfield, Virginia. Founded in 1939 by Clarence J. Robinson, the company primarily handled newsprint for The Washington Post, its owner until 2013. Robinson operated two deep-water berths alongside the Potomac River, one at the terminus of Oronoco Street, the other at the terminus of Duke Street. A railroad spur served the Oronoco facility. Vessels heading to or from the berths passed under the Woodrow Wilson Bridge, sometimes requiring the bridge's drawspan to open. In September 2013, the Washington Post Company sold the two waterfront facilities to real estate developers Nash Holdings.The company also operates two warehouse facilities in Springfield, Virginia. One of the Springfield warehouses is located along the Inner Loop of the Capital Beltway, and is frequently used as a landmark in local traffic reports. The Springfield facility is serviced by Norfolk Southern Railroad. Another warehouse facility was located at The Washington Post's printing plant in College Park, Maryland. The College Park plant was sold to the University of Maryland in 2010.
