I-73 is not an Interstate and is not in the Interstate system. In reality, I-73 is a National Highway System road and therefore subject to design flexibility. Predicting the effect of a proposed interstate on economic growth is a difficult task.
Economic development is dependent on many other factors.
In addition to transportation, a firm s location decision is influenced by other factors such as labor availability and cost, skill level, education and training, and physical space. Predicting business and mall development stemming from a proposed interstate is an insurmountable task. Consequently, the methodology adapted for assessing the impact of the potential Interstate 73 corridors focused on interchange development, specifically industries servicing highway users. Where, Why , by David T. Hartgen et al. He concluded that the economic development process is far too complex and the role of transportation is not dominant enough to causal relationships to be established.
