Sherman, a student at University of Pennsylvania, used a mapping software called ArcMap to examine special relations of highway tracts and their relation to separation of whites and non-whites. The results found that in southern states had more white people near the highways, while northern states had fewer white people. This can be explained by the southern and northern opposition during the Civil War.
For example, the construction of Interstate 74 created a clear racial boundary through Peoria, Illinois, which created neighborhood decay and high crime. The data from Illinois could easily be compared to Georgia’s interstate highway system and how it created different boundaries in Atlanta. This journal gives a more detailed explanation on how the construction of highways can lead to segregation in cities, intentional or not. This journal was written by an undergraduate student at the University of Pennsylvania, so it may not be perfect, although it is published to the public and backed my multiple professors, so it is safe to assume the journal is accurate. This source adds to the multiple examples collected from other sources of the ways that architecture has the ability to create segregation.
