Under the Bipartisan Infrastructure Law (BIL), the Build America Bureau can now consider Transportation Infrastructure Finance and Innovation Act (TIFIA) loans for airport-related projects, as defined in section 40117(a) of title 49. In addition, the Bureau can consider TIFIA or RRIF loans to support surface transportation projects at airports (such as consolidated rental car facilities and intermodal facilities) through other eligibilities as well. We encourage early coordination with the Bureau, so that we can help identify applicable requirements and potential opportunities.  As noted in the Credit Programs Guide, “…DOT expects recipients of TIFIA and RRIF credit assistance to comply with the domestic steel, iron, and other manufactured products content requirements of the applicable modal agency…”  The same applies to Prevailing Wage, DBE, and other applicable provisions.

  • State DOTs
  • State Infrastructure Banks
  • Private Entities
  • Airport Authorities
