The construction of the Virginia approaches to Arlington Memorial Bridge was a 16-year road construction project to connect Arlington Memorial Bridge with roads in Arlington County, Virginia, in the United States. Initial design proposals were made in 1926, but extensive political wrangling and indecision delayed the project and even the new bridge itself, which finally opened in 1932 after a connection to the Arlington National Cemetery was made via Memorial Drive. Officials with Arlington County and the state of Virginia long debated whether to build new roads, which would be far more expensive yet a boon to the local economy, or simply connect existing ones. Federal money became available for building approaches in 1933, four years into the Great Depression. The first connection with the bridge opened in October 1938; a second connection opened in 1942 to link it to the Pentagon road network.

The construction of Arlington Memorial Bridge was a seven-year construction project in Washington, D.C., in the United States to construct the Arlington Memorial Bridge across the Potomac River. The bridge was authorized by Congress in February 1925, and was completed in January 1932. As a memorial, its decorative features were extensive and intricate, and resolving the design issues over these details took many years. Tall columns and pylons topped by statuary, Greek Revival temple-like structures, and statue groups were proposed for the ends of the bridge. Carvings and inscriptions were planned for the sides of the bridge, and extensive statuary for the bridge piers. The bridge itself took far longer than the anticipated two years. Problems were encountered in building the foundations, accidents occurred, and the construction of the bascule (or drawbridge) span was complex and lengthy. Even though the bridge was finished by January 1932, construction of the termini and completion of the memorial details took another six years. Budget problems created in part by the Great Depression meant that portions of the bridge project were never completed. Construction of the bridge's western terminus involved extensively enlarging an island in the Potomac River, building bridges between this island and the Virginia mainland, building a new ceremonial entrance at Arlington National Cemetery, and creating a memorial drive to connect the cemetery to the bridge. The bridge's eastern approaches were equally as complex, and required construction of a plaza to the west of the Lincoln Memorial, connecting the bridge to the Rock Creek and Potomac Parkway, and building a "watergate" (marble steps) to given the public access to the river. The bridge was added to the National Register of Historic Places in 1980.

The Arlington Memorial Bridge is a Neoclassical masonry, steel, and stone arch bridge with a central bascule (or drawbridge) that crosses the Potomac River at Washington, D.C., the capital of the United States. First proposed in 1886, the bridge went unbuilt for decades thanks to political quarrels over whether the bridge should be a memorial, and to whom or what. Traffic problems associated with the dedication of the Tomb of the Unknown Soldier in November 1921 and the desire to build a bridge in time for the bicentennial of the birth of George Washington led to its construction in 1932. Designed by the architectural firm McKim, Mead, and White, decorated with monumental statues depicting valor and sacrifice by sculptor Leo Friedlander, cast by Ferdinando Marinelli Artistic Foundry, Florence, Italy, Arlington Memorial Bridge defines the western end of the National Mall. The bridge's draw span was permanently closed in 1961 and replaced in 2018 by one that does not open.

Arlington Experimental Farm was a former federal agricultural research farm in Alexandria, Virginia that opened in 1900. It was established by an Act of Congress, moving the Department of Agriculture's main research from the National Mall to Arlington. It grew hemp beginning in 1903 (under the cultivation of Lyster Dewey), or 1914. In 1928, it was the largest United States Department of Agriculture experiment station in the Washington, D.C. area. USDA researcher Vera Charles also worked at the station, collecting Cannabis seeds from across America and studying pests and pathogens that could diminish hemp crop productivity. Cultivars developed at Arlington include Arlington, Chington, Ferramington, Kymington and Arlington; Chington and Kymington were adopted "extensively" by seed farmers producing hemp in Kentucky. The seeds were probably destroyed by the government in the 1980s.In the 1930s, research was transferred to Henry A. Wallace Beltsville Agricultural Research Center in Beltsville, Maryland. The land the farm had occupied became Arlington Farms temporary housing during World War II and was developed for the site of The Pentagon and its parking lots.

The Seabees Memorial is a sculpture and memorial to Seabees by Felix de Weldon, installed along Memorial Drive near the entrance of Arlington National Cemetery.

It was dedicated on Memorial Day 1974.

Arlington Cemetery is a side platformed Washington Metro station in Arlington, Virginia, United States.

The rest of the Blue Line's stations are shared with the Yellow Line to the south (except for two of the southernmost stations), and with the Silver Line and Orange Line to the north.

Lyndon Baines Johnson Memorial Grove on the Potomac is located on Columbia Island (renamed Lady Bird Johnson Park in 1968), in Washington, D.C. The presidential memorial honors the 36th President of the United States, Lyndon B. Johnson. The grove consists of two parts. The first area, commemorative in nature, is a Texas granite monolith surrounded by a serpentine pattern of walks and trails. The second area is a grass meadow and provides a tranquil refuge for reflection and rejuvenation of the spirit. The trails are shaded by a grove of hundreds of white pine and dogwood trees, and framed by azaleas and rhododendron. The memorial overlooks the Potomac River with a vista of the city of Washington. Visitors may listen to a recording made by Lady Bird Johnson at the entrance to the park facing The Pentagon. In the recording, the former First Lady talks about the creation of the park, the trees, and the views of major Washington D.C. landmarks.

John Ericsson Memorial, located near the National Mall at Ohio Drive and Independence Avenue, SW, in Washington, D.C., is dedicated to the man who revolutionized naval history with his invention of the screw propeller. The Swedish engineer John Ericsson was also the designer of USS Monitor, the ship that ensured Union naval supremacy during the American Civil War.The memorial was authorized by Congress August 31, 1916, and dedicated May 29, 1926 by President Calvin Coolidge and Crown Prince Gustaf Adolf of Sweden. Congress appropriated $35,000 for the creation of the memorial, and Americans chiefly of Scandinavian descent raised an additional $25,000. Constructed on a site near the Lincoln Memorial between September 1926 and April 1927, the pink Milford granite memorial is 20 feet (6.1 m) high with a 9-foot (2.7 m) diameter base. Sculpted by James Earle Fraser, it features a seated figure of Ericsson 6 feet 5 inches (1.96 m) high, and three standing figures representing adventure, labor, and vision. The national memorial is managed by National Mall and Memorial Parks.

The Victims of Terrorist Attack on the Pentagon Memorial is a memorial over a group burial site at Arlington National Cemetery in the United States. It commemorates the victims of the attack on the Pentagon, which was struck by a Boeing 757 commercial airliner hijacked by five al-Qaeda terrorists on September 11, 2001, killing 184 people (excluding the hijackers). The memorial specifically honors the five individuals for whom no identifiable remains were found. However, a portion of the remains of 25 other victims are buried at the site. The names of the 115 Pentagon employees and 10 contractors in the building, as well as the 53 passengers and six crew members aboard American Airlines Flight 77 (which crashed into the building) are inscribed on the memorial.

The Women In Military Service For America Memorial, also known as Military Women's Memorial, is a memorial established by the U.S. federal government which honors women who have served in the United States Armed Forces. The memorial is located at the western end of Memorial Avenue at the entrance to Arlington National Cemetery in Arlington County, Virginia, in the United States. The structure in which the memorial is housed was originally known as the Hemicycle, and built in 1932 to be a ceremonial entrance to the cemetery. It never served this purpose, and was in disrepair by 1986. Congress approved the memorial in 1985, and the Hemicycle approved as the site for the memorial in 1988. An open design competition was won by New York City architects Marion Weiss and Michael Manfredi. Their original design was leaked to the public, and caused significant controversy. Two years of fund-raising and design revision followed. A revised preliminary design was approved in July 1992, and the final design in March 1995. Ground was broken for the memorial in June 1995, and the structure was dedicated on October 18, 1997. The memorial is notable for its successful mixing of Neoclassical and Modern architecture. The memorial largely retained the Hemicycle, but added a widely praised skylight on the Hemicycle terrace that incorporates not only memorials to servicewomen but also acts as a transition to the memorial below. Construction of the memorial, however, generated a lawsuit when a nearby pylon (part of the gateway to the cemetery) was damaged. Raising funds to pay off the construction debt incurred by the memorial took several years.

Little Island is an island in the Potomac River in Washington, D.C., just south of Theodore Roosevelt Island and the Theodore Roosevelt Bridge.

The Lincoln Memorial is a US national memorial built to honor the 16th president of the United States, Abraham Lincoln. It is on the western end of the National Mall in Washington, D.C., across from the Washington Monument, and is in the form of a neoclassical temple. The memorial's architect was Henry Bacon. The designer of the memorial interior's large central statue, Abraham Lincoln (1920), was Daniel Chester French; the Lincoln statue was carved by the Piccirilli brothers. The painter of the interior murals was Jules Guerin, and the epitaph above the statue was written by Royal Cortissoz. Dedicated in May 1922, it is one of several memorials built to honor an American president. It has always been a major tourist attraction and since the 1930s has sometimes been a symbolic center focused on race relations. The building is in the form of a Greek Doric temple and contains a large seated sculpture of Abraham Lincoln and inscriptions of two well-known speeches by Lincoln, the Gettysburg Address and his second inaugural address. The memorial has been the site of many famous speeches, including Martin Luther King Jr.'s "I Have a Dream" speech delivered on August 28, 1963, during the rally at the end of the March on Washington for Jobs and Freedom. Like other monuments on the National Mall – including the nearby Vietnam Veterans Memorial, Korean War Veterans Memorial, and World War II Memorial – the national memorial is administered by the National Park Service under its National Mall and Memorial Parks group. It has been listed on the National Register of Historic Places since October 15, 1966, and was ranked seventh on the American Institute of Architects' 2007 list of America's Favorite Architecture. The memorial is open to the public 24 hours a day, and more than 7 million people visit it annually.
