 The US $ 1trn IIJA is designed to facilitate the refurbishment , expansion and modernisation of US transportation , water , broadband and energy infrastructure . One of the express policy goals of the IIJA is to enable the leveraging of federal funds to promote private investment . The IIJA does this in part by expanding the kinds of projects eligible for TIFIA funding ( although admittedly not as broadly as many in the industry had expected ) and introducing other changes to make the Program more agile .

As with transit-oriented projects , ( i ) to be eligible the airport project must have delivered a letter of interest to the Secretary and received the Secretary ’ s determination of eligibility by September 30 2025 and ( ii ) this category of projects will have the same yearly 15 % share of total TIFIA budget authorisation , and
