The Tampa Hillsborough Expressway Authority (THEA) owns and operates the Lee Roy Selmon Expressway. Since its establishment, THEA has been responsible for numerous roadway projects in Hillsborough County that have contributed to increased mobility for its patrons and the county as a whole. THEA retained the Center for Urban Transportation Research (CUTR) at the University of South Florida (USF) to estimate the economic impacts and benefits of its operations and infrastructure investments. This study estimated THEA’s contribution to local economic growth and the mobility benefits associated with its Selmon Expressway. Through its operations and strategic investments, THEA supports key industries, increases mobility, reduces business costs, and expands local business opportunities, ultimately leading to economic growth and improved standards of living.
