Old Hugh Howell Road, previously open for major events only. All of Stone Mountain Freeway is included as part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility. History Stone Mountain Freeway was under construction in 1967 along the same alignment as it travels today. By 1970, the highway was completed. Controversy The Stone Mountain Freeway shares state route number 10 with Freedom Parkway, a road in central Atlanta that connects with the Interstate Highway System at a major interchange on I-75/I-85 (the Downtown Connector). As that designation suggests, state officials originally intended the Stone Mountain Freeway to continue west, through Decatur, Druid Hills, and Candler Park, to downtown Atlanta. In pursuit of those plans, in 1969, the GDOT purchased an X-shaped swath of land designed to carry two roads: I-485, traveling from west to east, and another freeway connecting what are now SR 400 to the north and I-675 to the south. Neighborhood groups and local preservationists worked together to block road construction of the highways. After 20 years of litigation and political maneuvering, community groups and state and local officials in 1991 compromised and set much of the state-purchased right-of-way aside as parkland, later named Freedom Park. The land proposed as the interchange of the two cancelled highways, by then, had become the site of the Carter Center. Freedom Parkway – the last vestige of the planned downtown link of the Stone Mountain Freeway – opened in 1994.
