History
Road development in Fairfax County reflects early colonial routes, 19th-century turnpikes, and 20th-century suburbanization tied to events like the American Revolutionary War, American Civil War, and postwar growth related to National Capital Planning Commission policies. Historic roads such as portions of Braddock Road, Lee Highway, and Chain Bridge Road trace lines once used during the Battle of Fairfax Court House and movements connected to figures like George Washington and Robert E. Lee. Twentieth-century projects including the construction of Dulles Toll Road and the expansion of Interstate 495 (Capital Beltway) were influenced by federal programs under administrations like those of Franklin D. Roosevelt and Dwight D. Eisenhower and agencies such as the Public Works Administration.
