Planning for Metro began with the Mass Transportation Survey in 1955 which attempted to forecast both freeway and mass transit systems sufficient to meet the needs of the region projected for 1980. In 1959, the study's final report included two rapid transit lines which anticipated subways in downtown Washington. Because the plan called for extensive freeway construction within the District of Columbia, alarmed residents lobbied for federal legislation creating a regional transportation agency with a moratorium on freeway construction through July 1, 1962. The new agency, the National Capital Transportation Administration, issued a 1962 "Transportation in the National Capital Region" report, which did not include the route that became the Yellow Line. A central route under 7th Street in downtown was only added in 1967 primarily to serve the "inner city". In March 1968, the Washington Metropolitan Area Transit Authority (WMATA) board approved its Adopted Regional System (ARS) which included the Yellow Line from Franconia and Backlick Road (in Springfield) to Greenbelt.
