As part of its enactment of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), P.L. 109-59 in 2005, Congress directed the Secretary of Transportation to submit a biannual report summarizing the financial performance of the projects receiving assistance under TIFIA. This TIFIA Report to Congress constitutes the fifth submission from the U.S. Department of Transportation (DOT). The report provides current financial performance on the TIFIA portfolio, information on the policy underpinnings of the TIFIA program, an overview of the benefits of TIFIA support for borrowers, and a summary of the status of all active TIFIA credit agreements. In addition to information noted above, the 2012 report to Congress also addresses issues that have arisen since the 2010 report was issued.
