Federal funding for highways is provided to the states mostly through a series of grant programs known as the Federal-Aid Highway Program, administered by the Department of Transportation's (DOT) Federal Highway Administration (FHWA). In 2005, the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) authorized $197.5 billion for the Federal-Aid Highway Program for fiscal years 2005 through 2009. The program operates on a "user pay" system, wherein users contribute to the Highway Trust Fund through fuel taxes and other fees. The distribution of funding among the states has been a contentious issue. States that receive less than their highway users contribute are known as "donor" states and states that receive more than their highway users contribute are known as "donee" states. GAO was asked to examine for the SAFETEA-LU period (1) how contributions to the Highway Trust Fund compared with the funding states received, (2) what provisions were used to address rate-of-return issues across states, and (3) what additional factors affect the relationship between contributions to the Highway Trust Fund and the funding states receive. To conduct this review, GAO obtained and analyzed data from FHWA, reviewed FHWA and other reports, and interviewed FHWA and DOT officials. DOT reviewed a draft of this report and provided technical comments, which we incorporated as appropriate.

Since 2005, every state received as much or more funding for highway programs than they contributed to the Highway Account of the trust fund. This was possible because more funding was authorized and apportioned than was collected from the states and the fund needed to be augmented with general revenues. If the percentage of funds states contributed to the total is compared with the percentage of funds states received (i.e., relative share), then 28 states received a relatively lower share and 22 states received a relatively higher share than they contributed. Thus, depending on the method of calculation, the same state can appear to be either a donor or donee state. The Equity Bonus Program was used to address rate-of-return issues. It guaranteed a minimum return to states, providing them about $44 billion. Nearly all states received Equity Bonus funding and about half received a significant increase, at least 25 percent, over their core funding. The infusion of general revenues into the Highway Trust Fund affects the relationship between funding and contributions, as a significant amount of highway funding is no longer provided by highway users. Since fiscal year 2008, Congress has transferred nearly $30 billion of general revenues to address shortfalls in the highway program when more funding was authorized than collected. Using rate of return as a major factor in determining highway funding poses challenges to introducing a performance and accountability orientation into the highway program; rate-of-return calculations in effect override other considerations to yield a largely predetermined outcome--that of returning revenues to their state of origin. Because of these and other challenges, funding surface transportation programs remains on GAO's High-Risk list.
