Changes in Birmingham Following the Interstate Highway: Methodology
Historical research has shown that the construction of the U.S. Interstate Highway System from the 1950's to the 1970's disrupted many urban communities leading to worsening racial inequalities, injustices, and segregation. Birmingham, Alabama, specifically the I-20 and I-65 Interstate exchange, serves as a case study area to document the changes that occurred following the construction. Aerial photography and Census data were used to compare the area of interest before and after the establishment of the highway. The aerial photography documented land use/land cover (LULC) alterations and the Census data measured demographic changes. Usage of geospatial data such as these enables quantitative and qualitative assessment of the impacts immediately surrounding the I-20 and I-65 Interstate exchange since its construction. A case study like the I-20 and I-65 Interstate exchange serves as evidence that transportation planning practices often have unequal and negative impacts on their surrounding communities.
