Sustainability of Moving Atlanta Interstate Highways within the Perimeter Underground: Preliminary Detour Analysis

The interstate highway system within the Atlanta perimeter plays an important role in the daily lives of residents. Today, they are the most heavily traveled roadways in the city due to suburban sprawl. However, the interstate highway system greatly disfigures and disconnects the city. Moving all interstate highways within the perimeter underground can increase the connections and communications between different sub-communities, especially for those who are separated by current interstate highways. The authors used the road network data, provided by “open street map” data, to analyze the spatial patterns of the road network’s Detour Index. A new reconnected road network was created after hypothetically moving the interstate highways underground, by reconnecting roads that were cut or eliminated during construction of the interstates, based on an aerial image from 1952 of the Vine City District. The change in Detour Index as a result of reconnecting those roads was analyzed. The results show that it can increase the connectivity of the road network in areas adjacent to the interstates, reducing the travel distance to places on the other side of where the interstates currently exist. From this point of view, moving interstates underground can yield a more equitable transportation systems, and may lead to a more sustainable highway system than the current one.
