East Capitol Street in the context of "United States Capitol"

The Thomas Jefferson Building, also known as the Main Library, is the oldest of the Library of Congress buildings in Washington, D.C. Built between 1890 and 1897, it was initially known as the Library of Congress Building. In 1980, the building was named in honor of Thomas Jefferson (1743–1826), a Founding Father, the principal author of the Declaration of Independence, and the third U.S. president. In 1815, the purchase of Jefferson's book collection formed a core foundation for the library's collection.

The building is located on First Street, S.E. between Independence Avenue and East Capitol Street in the federal national capital city of Washington, D.C., across from the United States Capitol on Capitol Hill. It is adjacent to the library's additional buildings in the Library of Congress complex, the John Adams Building (built in the 1930s) across Second Street, and the James Madison Memorial Building (built in the 1970s) across Independence Avenue to the south.

Southeast (SE or S.E.) is the southeastern quadrant of Washington, D.C., the capital of the United States, and is located south of East Capitol Street and east of South Capitol Street. It includes the Capitol Hill, Hill East, and Anacostia neighborhoods, the Navy Yard, the Joint Base Anacostia-Bolling (JBAB), the U.S. Marine Barracks, the Anacostia River waterfront, Eastern Market, the remains of several Civil War-era forts, historic St. Elizabeths Hospital, RFK Stadium, Nationals Park, and the Congressional Cemetery. It also contains a landmark known as "The Big Chair," located on Martin Luther King Jr. Avenue. The quadrant is split by the Anacostia River, with the portion that is west of the river sometimes referred to as "Near Southeast". Geographically, it is the second-smallest quadrant of the city.

Independence Avenue is a major east–west street in the southwest and southeast quadrants of the city of Washington, D.C., in the United States, running just south of the United States Capitol. Originally named South B Street, Independence Avenue SW was constructed between 1791 and 1823. Independence Avenue SE was constructed in pieces as residential development occurred east of the United States Capitol and east of the Anacostia River. Independence Avenue received its current name after Congress renamed the street in 1934.

Independence Avenue SW originally had its western terminus at 14th Street SW, but was extended west to Ohio Drive SW between 1941 and 1942. The government of the District of Columbia renamed the portion of the road in the southeast quadrant of the city, west of the Anacostia River, in 1950. Independence Avenue SE encircles the southern end of the former RFK Stadium before ending at East Capitol Street near the Whitney Young Memorial Bridge.

The John Adams Building is the second-oldest of the buildings of the Library of Congress of the United States. Built in the 1930s, it is named for John Adams, the second president, who signed the law creating the Library of Congress in 1800. The building is in the Capitol Hill district of Washington D.C. next to the library's main building (now known as the Thomas Jefferson Building) in the Capitol Complex. The Adams building opened to the public on April 5, 1939, and before being named for the president in 1980, was simply called The Annex building. It is designed in a restrained but very detailed Art Deco style and faced in white Georgia marble. It is located on Second Street SE between Independence Avenue and East Capitol Street in Washington, DC.

Northeast (NE or N.E.) is the northeastern quadrant of Washington, D.C., the capital of the United States. It encompasses the area located north of East Capitol Street and east of North Capitol Street.

Robert F. Kennedy Memorial Stadium, commonly known as RFK Stadium and originally known as District of Columbia Stadium, was a multi-purpose stadium in Washington, D.C.. It was located along the Anacostia River on East Capitol Street in the city's Hill East neighborhood. The stadium was in operation from 1961 to 2019, with deconstruction commencing in 2025 ahead of a $3.7 billion stadium to replace it at the site. RFK Stadium was one of the first large stadiums designed to host both baseball and football, and was among the first to use what became known as the cookie-cutter design.

RFK Stadium was home to a National Football League (NFL) team, two Major League Baseball (MLB) teams, five professional soccer teams, two college football teams, and a USFL team. It hosted college football, college soccer, baseball exhibitions, boxing matches, a cycling race, an American Le Mans Series auto race, marathons, and dozens of concerts. Significant events hosted include five NFC Championship Games, two MLB All-Star Games, several FIFA World Cup matches, nine 1996 Olympic soccer matches, three MLS Cups, and two MLS All-Star Games.

The Whitney Young Memorial Bridge is a bridge that carries East Capitol Street across the Anacostia River and Kingman Lake in Washington, D.C. in the United States. Finished in 1955, it was originally called the East Capitol Street Bridge. It was renamed for civil rights activist Whitney Young in early 1974. The bridge is 1,800 feet (550 m) long, its six lanes are 82 feet (25 m) wide, and it has 15 spans resting on 14 piers. It passes over the southern end of Kingman Island and splits into C Street NE and Independence Avenue SE at the site of the former Robert F. Kennedy Memorial Stadium and future New Commanders Stadium on its western end.
