This thesis defines the way that roadside landscapes can become a model of sustainable landscape design along the highways of the United States. The construction and maintenance of roads and roadsides has been recognized as a cause of habitat fragmentation and pollution. Increasing awareness of these negative effects on the environment has led to the creation of legislation and regulations that encourage environmentally sensitive planning and design, yet few state programs in Georgia exist involving this important public landscape. This study reviews the history of roadside landscape design as it has emerged in American history. Next, a review of selected state DOT programs, projects, and guidelines highlights innovative ideas across the United States. Then, roadside typologies are presented for an 18-mile section of Georgia I-85 highway associated with The Ray. Finally, ecological design recommendations are identified and illustrated for each roadside typology of the study area. These typologies can serve as a useful framework for piedmont roadsides across the Southeast United States.
