Abstract:

This report explores the way in which TDOT investments in state roads and interstate highways affect economic growth in Tennessee counties as measured by nonfarm employment, business establishments, personal income, per capita personal income and population. The goal is to estimate the private sector economic returns to public sector transportation investments. The analysis relies on a complete inventory of major state road and interstate projects supported by TDOT between 2001 and 2018 that are linked to counties across the state. We find that both descriptive methods and rigorous statistical modeling fail to identify strong linkages between roadway investments in Tennessee and county-level measures of economic wellbeing. Descriptive methods reveal a mix of high return and low return investment projects in the same counties across the state. In the econometric models, the null findings are robust across a wide range of different model specifications. In virtually none of the modeling did we find statistically valid positive associations between transportation investments and economic outcomes.
