On August 10, the U.S. Senate overwhelmingly passed the Infrastructure Investment and Jobs Act (IIJA), a $1.2 trillion infrastructure bill negotiated by the Biden Administration and a bipartisan group of senators. Nineteen Republican Senators joined 50 Democrats to pass the bill and send it to the House of Representatives.

On November 5, the House passed the IIJA without amendment and sent the bill to President Biden to be signed into law. Thirteen House Republicans joined 215 Democrats to pass the bill.

On November 15, 2021 President Biden signed the IIJA into law – PL 117-58.

The IIJA includes a 5-year surface transportation bill. The highway provisions are based on the 5-year highway bill approved by the Senate Environment and Public Works Committee earlier in 2021. The rail and safety provision are based on the 5-year bill approved by the Senate Commerce Committee earlier in 2021.


IIJA Guaranteed Transportation Funding (HTF + Advanced Appropriations) over 5 years

The IIJA provides $550 billion in new infrastructure spending above current baseline levels. Of that amount, $274 billion is allocated to transportation programs. When added to baseline spending, the bill provides $567 billion in guaranteed transportation funding over five years. Additional funding also may be provided to several program through the annual appropriations process.

$274 billion of the $550 was included for USDOT in the bill.

  • $89.8 billion was used to allow increased Highway Trust Fund contract authority over the five-year period 2022-2026.
  • $184.1 billion is provided in direct appropriations (not just for highways and transit and safety, but for railroads and airports and multimodal grants and ports), to be released in five equal installments on October 1 of each year for the next five years.

When added to the $293.5 billion baseline funding (last year of the FAST Act: $58.708 x 5) total guaranteed funding over 5 years is $567.5 billion.
