“Presentation by Chad Shirley, CBO’s Deputy Assistant Director for Microeconomic Studies, at the Transportation Policy & Finance Summit of the International Bridge, Tunnel and Turnpike Association (IBTTA). Federal spending on highways (or, synonymously, roads) totaled $46 billion in 2014, roughly a quarter of total public spending on highways. But that spending does not correspond very well with how the roads are used and valued. This presentation illustrates how spending on highways is related to their use and performance, and it examines three approaches that the Congress could consider to make highway spending more productive.”
