East Capitol Street is a major street that divides the northeast and southeast quadrants of Washington, D.C., United States. It runs due east from the United States Capitol to the DC-Maryland border. The street is uninterrupted until Lincoln Park then continues eastward around the RFK Stadium campus. East of the stadium, East Capitol crosses the Anacostia River via the Whitney Young Memorial Bridge and then goes underneath Route 295 before crossing into Prince George's County, Maryland, where it becomes Maryland State Highway 214.

The western stretch of East Capitol Street passes through the Capitol Hill and Hill East neighborhoods. East Capitol Street is home to the Folger Shakespeare Library, US-Asia Institute, Les Aspin Center for Government, East Capitol Street Car Barn, D.C. Armory, and the future New Commanders Stadium.

The Washington Metro, often abbreviated as the Metro and formally the Metrorail, is a rapid transit system serving the Washington metropolitan area of the United States. It is administered by the Washington Metropolitan Area Transit Authority (WMATA), which also operates the Metrobus service under the Metro name. Opened in 1976, the network now includes six lines, 98 stations, and 130 miles (210 km) of route.

Metro serves Washington, D.C. and the states of Maryland and Virginia. In Maryland, Metro provides service to Montgomery and Prince George's counties; in Virginia, to Arlington, Fairfax and Loudoun counties, and to the independent city of Alexandria. The system's most recent expansion, which is the construction of a new station (and altering the line), serving Potomac Yard, opened on May 19, 2023. It operates mostly as a deep-level subway in more densely populated parts of the D.C. metropolitan area (including most of the District itself), while most of the suburban tracks are at surface level or elevated. The longest single-tier escalator in the Western Hemisphere, spanning 230 feet (70 m), is located at Metro's deep-level Wheaton station.

Fairfax County, officially the County of Fairfax, is a county in the Commonwealth of Virginia. With a population of 1,150,309 as of the 2020 census, it is the most populous county in Virginia, the most populous jurisdiction in the Washington metropolitan area, and the most populous location in the Washington–Baltimore combined statistical area. The county seat is Fairfax; however, because it is an independent city under Virginia law, the city of Fairfax is not part of the county.

The county is part of the Northern Virginia region and forms part of the suburban ring of Washington, D.C., the nation's capital. The county is predominantly suburban with some urban and rural pockets. It borders Montgomery County, Maryland to its north, Falls Church, Alexandria, Arlington County, and Prince George's County, Maryland to its east, Charles County, Maryland to its southeast, Prince William County to its southwest, and Loudoun County to its northwest.

Pennsylvania Avenue is a primarily diagonal street in Washington, D.C., that connects the United States Capitol with the White House and then crosses northwest Washington, D.C., to Georgetown. Traveling through southeast Washington from the Capitol, it enters Prince George's County, Maryland, and becomes MD Route 4 (MD 4) and then MD Route 717 in Upper Marlboro, and finally Stephanie Roper Highway.

The section of the avenue between the White House, which is sometimes referred to by its address "1600 Pennsylvania Avenue", and the Capitol forms the basis for the Pennsylvania Avenue National Historic Site and is sometimes referred to as "America's Main Street"; it is the location of official parades and processions, and periodic protest marches. Pennsylvania Avenue is an important commuter road and is part of the National Highway System.

The Anacostia River /ænəˈkɒstiə/ is a river in the Mid-Atlantic region of the United States. It flows from Prince George's County in Maryland into Washington, D.C., where it joins with the Washington Channel and ultimately empties into the Potomac River at Buzzard Point. It is about 8.7 miles (14.0 km) long. The name "Anacostia" derives from the area's early history as Nacotchtank, a settlement of Necostan or Anacostan Native Americans on the banks of the Anacostia River.

Heavy pollution in the Anacostia and weak investment and development along its banks made it "D.C.'s forgotten river". More recently, however, private organizations; local businesses; and the D.C., Maryland, and federal governments have made efforts to reduce pollution and protect the ecologically valuable Anacostia watershed.

Maryland Route 214 (MD 214) is a state highway in the U.S. state of Maryland. Known for most of its length as Central Avenue, the highway runs 24.97 miles (40.19 km) from Southern Avenue and East Capitol Street at the District of Columbia boundary in Capitol Heights east to Beverley Beach. MD 214 connects the central Prince George's County suburbs of Capitol Heights, Seat Pleasant, Largo, and Bowie with the southern Anne Arundel County communities of Davidsonville and Edgewater and several beach villages along the Chesapeake Bay. The highway connects Interstate 95 (I-95)/I-495 (Capital Beltway) to Northwest Stadium, Six Flags America, and several stations of the Washington Metro's Blue and Silver lines, which the route parallels between Capitol Heights and Largo.

MD 214 was constructed as part of three state highways. MD 214 proper was constructed in the mid-1910s from Washington to Largo and extended east to what is now U.S. Route 301 (US 301) through the 1920s. MD 254 was built from MD 2 in Edgewater west to Davidsonville in the early to mid-1920s. MD 253 was constructed from the modern end of the highway southeast to Beverley Beach between the mid-1920s and early 1930s. The gap between Bowie and Davidsonville was filled in the mid-1930s; MD 214 was extended east across a new Patuxent River bridge and took over MD 254's route to Edgewater. In the late 1940s, MD 214 was relocated through Edgewater and extended along most of MD 253 to Beverley Beach. The state highway was widened in Prince George's County in the 1930s and again in the 1950s, and from US 301 to MD 2 in the 1940s and again in the 1950s. MD 214 was expanded to a divided highway at US 301 in the late 1950s, at its interchange with the Capital Beltway in the mid-1960s, and when it bypassed Capitol Heights in the late 1960s. The two-lane gaps between those three segments were filled in the 1980s and 1990s.

The Orange Line is one of the six rapid transit lines of the Washington Metro system, consisting of 26 stations in Fairfax County and Arlington in Northern Virginia; Washington, D.C.; and Prince George's County, Maryland, United States. The Orange Line runs from Vienna in Fairfax County to New Carrollton in Prince George's County. Half of the line's stations are shared with the Blue Line and all but three stations (Vienna, Dunn Loring, and West Falls Church) are shared with the Silver Line. Orange Line service began on November 20, 1978.

Trains run every 10 minutes during weekday rush hours, every 12 minutes during weekday off-peak hours and weekends, and every 15 minutes daily after 9:30 pm.

The Silver Line is a rapid transit line of the Washington Metro system, consisting of 39 stations in Loudoun County, Fairfax County and Arlington County, Virginia, Washington, D.C., and Prince George's County, Maryland. The Silver Line runs from Ashburn in Loudoun County, Virginia to Largo and New Carrollton in Prince George's County, Maryland. Five stations, from both lines' eastern terminus at Largo to Benning Road, are shared with the Blue Line alone; five stations are shared with the Orange Line alone from both lines eastern terminus at New Carrollton to Minnesota Avenue; thirteen stations, from Stadium–Armory to Rosslyn, with both the Orange Line and Blue Lines; and five stations from Court House to East Falls Church with the Orange Line alone. Only the 11 stations from McLean to Ashburn are exclusive to the Silver Line. Five of these 11 stations began service on July 26, 2014 as Phase 1, and six began service as Phase 2 on November 15, 2022.

The 11.7-mile (18.8 km) portion of the Silver Line between its split from the Orange Line and Wiehle–Reston East is entirely in Fairfax County, Virginia and was constructed as Phase 1 of the Dulles Corridor Metrorail Project. Phase 2 expanded the line another 11.5 miles (18.5 km) to Ashburn in Loudoun County via Dulles International Airport. The $6.01 billion, 23.1-mile Dulles Corridor Metrorail Project is Metro's largest expansion by route mileage since its inception in 1976.
