This year, the federal government gave $45.6 billion in highway “formula” funding to the 50 states and the District of Columbia. The state-by-state distribution of this money was based almost entirely on how the states fared on a variety of real-world metrics back in calendar year 2007, adjusted at the time for the need to keep certain states happy at the percentages of total formula funding they received in the 1980s and 1990s, and how well each state’s Congressional delegation did in securing home-state earmarks in the 2005 SAFETEA-LU pork-barrel bonanza. The only factor that is allowed to change with the times is a requirement for each to get back 95 percent of the dollars they paid in federal gasoline, diesel and trucking excise taxes in the most recent prior year, which currently only benefits Texas.
Congress ordered the establishment of the first-ever national performance standards and measures for highways and bridges in 2012. Congress said the purpose of those standards and measures was to “transform the Federal-aid highway program and provide a means to the most efficient investment of Federal transportation funds by refocusing on national transportation goals, increasing the accountability and transparency of the Federal-aid highway program, and improving project decision-making through performance-based planning and programming.” But seven years later, those performance measures and standards have nothing at all to do with how the federal government distributes highway funding.
Can we do better?
This paper examines the past, present, and possible future of the distribution of Federal-aid highway funding to states. For the first seven decades of the Federal-aid highway program, while the apportionment formulas were always set by Congress and involved political compromises, the formulas were based on constantly updated real-world factors like state population, lane-miles, miles-traveled on the various highway systems, fuel usage and tax payments, and local air quality. Construction of the Interstate System was distributed based on the periodically updated cost estimate for completion of each state’s roads on the Interstate map.
But starting in the 1980s, as construction of the Interstate System wound down, states and their Congressional delegations seemed to lose sight of the shared sacrifice inherent in the Interstate program and instead focused more and more on increasing their state’s share of total funding in each successive authorization bill at the expense of other states. Naked political muscle replaced objective metrics, until “minimum guarantees,” “hold harmless” provisions, and an ever-increasing number of earmarks dominated the old program in the 2005 SAFETEA-LU law.
