This study aimed to fill this gap in transport research by providing a holistic look at the regional changes that occurred due to new transport infrastructure construction in Northwest Arkansas between 1980 and 2011. The National Land Cover Database was used to create a time-series of land cover across the region between 1992 and 2011. These data were then used to predict future growth in the region. Additionally, growth patterns of the four largest cities (Bentonville, Fayetteville, Rogers, and Springdale) were studied, and monocentricity values for the region were calculated to study population movement. Data on income, retail trade, gross merchandise trade, and worker flows were used to economically characterize the region for the time period of study. The results show that development is mostly occurring on top of agricultural land, though higher intensity developments do are often replacing lower intensity uses. A third of all development occurs within a half-mile of a US highway, with a third of these developments occurring within a half-mile of I-540/I-49. The main cities of Northwest Arkansas are expanding their borders at a rate that maintains roughly 50% developed land cover, such expansion and land use track could make for an easily quantifiable measure of urban sprawl that could be combined with other factors to better quantify sprawl than current methods. Economically, Madison County, AR and McDonald County, MO both saw up to 80% permanent drops in economic trade that align with major milestones in the construction of I-540. This is further supported by a ten point drop in residents who chose to work outside of Benton or Washington County once the bypass was completed. Meanwhile, Benton County saw a short-lived doubling of trade, and Washington County saw a smaller, lagged effect that was also not permanent. These findings suggest that the I-540/I- 49 created severe spatial and economic competition in the region with no obvious winner. Acknowledgements I’d like to express my gratitude to the multitude of people that made this thesis possible. Dr. Tom Paradise for bringing me into the program and allowing me to work under him. Dr. Fiona Davidson for guiding me along the way and helping me work through the many roadblocks that came up as I developed the earliest forms of this thesis. Dr. Xuan Shi for helping me with the many quirks and oddities that can come up when working with geospatial data. To everyone in my office, who have all at some point discussed my research with me and provided some much needed input, especially Jamey Voorhees, for his historical knowledge on the region, and Bradley Wilson, for helping me during the writing of this thesis. Dedication This thesis is dedicated to my always loving and supportive family. Table of Contents 1.
