Revolt! How People, Policy, and Protests Shaped Atlanta’s System explores the role of public participation in the transportation decision-making process in Atlanta since the 1940s. Engaging traditional narratives of the city’s urban development, Revolt! argues that public participation has played and continues to play a more significant role in the development of Atlanta’s highways than previously understood. Starting with the introduction of the H.W. Lochner and Company’s transportation plan following World War II, the city was transformed through highway construction and urban renewal. However, public participation in the transportation decision-making process was critical in this transformation. Civil Rights organizations led the earliest resistance to highways and mass displacement, as the Downtown Connector curved through majority Black neighborhoods east of Atlanta’s central business district. By the 1960s, highways planned for neighborhoods east of downtown were generating organized protests. Building on past efforts, white neighborhood activist groups formed advocacy networks and harnessed new federal policies born from the harms caused by interstate highways. Battles over Interstate 485, the Stone Mountain Freeway, the Great Park, and the Presidential Parkway redefined the local and state power structure and led to a new, interracial political coalition in the city. Today, modern infrastructure projects such as the Stitch, an initiative to cap a portion of the Downtown Connector with green space, draw on the intertwined legacies of displacement and neighborhood activism to reconnect and revitalize the city. Revolt! identifies many of the individuals and groups and the strategies and tools they used to resist the impact of highway construction at each stage. The study’s chronological approach to urban history reveals consistent themes of race, economic interests, housing, and community.
