Overbuilt: The High Costs and Low Rewards of US Highway Construction, transportation planning expert Erick Guerra describes how the US roadway system became overbuilt, how public policy continues to encourage overbuilding, the scale and consequences of overbuilding, and how we can rethink our approach to highway building in the US.
Guerra explains that highway overbuilding stems from the institutions, finance mechanisms, and evaluation metrics developed in the first half of the twentieth century. While more funds are set aside for transit, walking, biking, and beautification, the investment paradigm has not changed. Planners and engineers have not adjusted the tools they use to determine which roads should be built, rebuilt, or widened and why.
Despite having too much roadway, the country is still operating in construction mode, using the same basic approach used to finance and build the interstate system quickly, Guerra states. The interstate was completed more than three decades ago.
Overbuilt argues convincingly that it is time to move on.
