The TIFIA Program Guide, application form and related materials are all currently under review and being revised to reflect MAP-21 changes. Please check the site regularly for updated information.
The Transportation Infrastructure Finance and Innovation Act of 1998 (TIFIA) was originally authorized under the Transportation Equity Act for the 21st Century (TEA-21). TIFIA was reauthorized and amended in 2005 by the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU). This section of the TIFIA website includes relevant excerpts of the TEA-21 authorizing legislation and accompanying technical corrections as well as relevant legislative excerpts from SAFETEA-LU. It should be noted that SAFETEA-LU's reauthorization of TIFIA resulted in a renumbering of its sections within Title 23 of the U.S. Code from §§ 181-189 to §§ 601-609.
The USDOT published its rules for the TIFIA program in the Code of Federal Regulations (49 CFR 80) one year after the passage of TEA-21 in June 1999 and revised them in July 2000. Public notices for these acts of rulemaking are provided under Federal Register Notices, along with other announcements related to the TIFIA program. The TIFIA regulations have not been updated to reflect changes enacted in Public Law 109-59, SAFETEA-LU. Where the statute and the regulation conflict, the statute takes precedence.
