On July 6, 2012, President Obama signed H.R. 4348, the Moving Ahead for Progress in the 21st Century Act (MAP–21). MAP-21 authorizes federal highway and transit programs through September 30, 2014, with the first three months (July-September 2012) being a three-month extension of SAFETEA-LU combined with a new 2-year authorization beginning October 1.

Contract authority will fund highway and transit formula programs. Transit new starts, research and administrative expenses will be funded through annual appropriations from general Treasury funds. The bill provides modest annual inflationary increases.

Program FY 2012 FY 2013 FY 2014
Highway obligation limit $39.144 billion $39.699 billion $40.256 billion
Exempt Contract Authority $0.639 billion $0.639 billion $0.639 billion
Transit program
Formula programs $8.361 billion $8.478 billion $8.595 billion
Capital Investment Grants $1.955 billion $1.907 billion $1.907 billion
Research & training $0.044 billion $0.089 billion $0.089 billion
Administration $0.099 billion $0.104 billion $0.104 billion
Transit total $10.459 billion $10.578 billion $10.695 billion

MAP-21 is financed by extending existing motor fuel taxes through September 2016, two years longer than the spending provisions, and by a two-year $18.8 billion infusion of general revenue. Additional funding results from the adoption of Senate provisions dealing with the Leaking Underground Storage Tank Trust Fund, reform of the Pension Benefit Guarantee and ERISA programs, taxation of the transfer of excess pension assets and tobacco tax reforms.

MAP-21 provides that in fiscal 2013, each state will receive a total apportionment of highway program funds equal to its total apportionment in FY 2012. For FY 2014, the apportionment formula will begin with the fiscal 2012 shares followed by an adjustment to assure that no state receives less than 95 percent of its contribution to the Highway Trust Fund. Once the apportionment of funds among the states is determined, each state's total will be divided among programs using the following formula:

  • CMAQ and Metropolitan Planning– the same share of the state's total apportionment as in FY 2009;
  • 63.7 percent of the remaining funds to the National Highway Performance Program;
  • 29.3 percent of the remaining funds to the Surface Transportation Program; and
  • 7 percent of remaining funds to the Highway Safety Improvement Program.

Beginning October 1, 2012, MAP-21 collapses SAFETEA-LU program structure into five main programs:

  • National Highway Performance Program;
  • Surface Transportation Program;
  • Highway Safety Improvement Program;
  • Congestion Mitigation and Air Quality Program; and
  • Metropolitan Planning.
