ALEXANDRIA : Alexandria is an independent city in the Commonwealth of Virginia. As of the 2000 census, the city had a total population of 128,283.[citation needed] Located along the Western bank of the Potomac River, Alexandria is approximately 6 miles (9.6 kilometers) south of downtown Washington, D.C.

Like the rest of Northern Virginia, as well as central Maryland, modern Alexandria has been shaped by its proximity to the nation's capital. It is largely populated by professionals working in the federal civil service, the U.S. military, or for one of the many private companies which contract to provide services to the federal government. The latter are known locally as beltway bandits, after the Capital Beltway, an interstate highway that circles Washington, D.C. One of Alexandria's largest employers is the U.S. Department of Defense. Others include the Institute for Defense Analyses and the Center for Naval Analyses. In 2005, the United States Patent and Trademark Office moved 7,100 employees from 18 separate buildings in nearby Crystal City into a new headquarters complex in the city.

Alexandria is home to numerous trade associations, charities, and non-profit organizations including the national headquarters of groups such as the Salvation Army. Alexandria is bisected north and south by State Route 7, known in most of the city as the major thoroughfare of King Street. Interstate 95/495 (the Capital Beltway), including the Woodrow Wilson Bridge over the Potomac River, approximately parallels the city's southern boundary with Fairfax County. Interstate 395 crosses through the western part of the city. Other major routes include U.S. 1 (named Jefferson Davis Highway, and Patrick and Henry Streets after Patrick Henry and Richmond Highway), the George Washington Memorial Parkway, and Duke Street (State Route 236).Alexandria is located just south of Ronald Reagan Washington National Airport in Arlington County. Alexandria Union Station, the city's historic train station, is served by both Amtrak intercity and Virginia Railway Express regional rail service. The station is directly adjacent to the King Street Metrorail station, at the convergence of the Blue and Yellow Lines. Three other Metrorail stations that lie within the city limits are Braddock Road, Van Dorn Street, and Eisenhower Avenue. The city government operates its own mass transit system, the DASH bus, connecting points of interest with local transit hubs. Metrobus, Washington Metro, and the Virginia Railway Express better known as the VRE also serves Alexandria. The City also offers a free trolley service on King Street from the King Street Metro Station to the Waterfront and a water taxi to and from the National Harbor development in Prince George's County, Maryland.
