The Transportation Infrastructure Finance and Innovation Act (TIFIA) Program is a federal credit assistance program from the Department of Transportation that funds large-scale surface transportation infrastructure projects of regional and national significance.
TIFIA provides low-interest credit assistance — including loans, loan guarantees, and lines of credit — at fixed U.S. Treasury rates, financing up to 49 percent of eligible project costs. Eligible projects include highways, transit systems, railroads, intermodal freight facilities, and port access improvements.
Applicants may include state and local governments, transit agencies, railroad companies, special authorities, special districts, and private entities. With up to $5 billion in federal obligations available, repayment periods can extend up to 35 years — or 75 years in some cases — with deferral options for up to five years after project completion.

_ * Low, fixed interest rate (_US Treasury rates_) * Finance up to 49 percent of eligible project costs * Interest does not accrue until proceeds are drawn * Up to 35 year repayment period _(in some cases, up to 75 years)_ * Deferrable for five years after substantial project completion The Transportation Infrastructure Finance and Innovation Act (TIFIA) program provides credit assistance for qualified projects of regional and national significance.
Many large-scale, surface transportation projects - highway, transit, railroad, intermodal freight, and port access - are eligible for assistance. Eligible applicants include state and local governments, transit agencies, railroad companies, special authorities, special districts, and private entities.
The TIFIA credit program is designed to: _Fill market gaps and leverage substantial private co-investment through supplemental,subordinate investment in critical improvements to the nation's transportation system. _ TIFIA credit assistance is often available on more advantageous terms than in the financial market, making it possible to obtain financing for needed projects when that financing might not otherwise be available.
For more information, please see theTIFIA Credit Program Overview, which summarizes the basic purpose, processes and historical activity of the program. ***Important Notice:**Revenue-backed public-private partnership (P3) projects' funding plans are required to include at least 25 percent of total eligible project costs in private co-investment to be eligible for an up to 49 percent TIFIA loan.
Additionally, some projects may require further analysis to be eligible for financing. Click here to learn more. * #### Pipeline of projects that have completed Letters of Interest or Applications can be viewed on the Project Information Page.
Credit Assistance and Benefits The TIFIA credit program offers three distinct types of financial assistance designed to address the varying requirements of projects throughout their life cycles: **Secured (direct) loan**- Offers flexible repayment terms and provides combined construction and permanent financing of capital costs. Maximum term of 35 years from substantial completion.
Repayments can start up to five years after substantial completion to allow time for facility construction and ramp-up. **Loan guarantee**- Provides full-faith-and-credit guarantees by the Federal Government and guarantees a borrower's repayments to non-Federal lender. Loan repayments to lender must commence no later than five years after substantial completion of project.
**Standby line of credit**- Represents a secondary source of funding in the form of a contingent Federal loan to supplement project revenues, if needed, during the first 10 years of project operations, available up to 10 years after substantial completion of project. The amount of Federal credit assistance may not exceed 49 percent of total reasonably anticipated eligible project costs, with limited exceptions.
The exact terms for each loan are negotiated between the USDOT and the borrower, based on the project economics, the cost and revenue profile of the project, and any other relevant factors. For example, USDOT policy does not generally permit equity investors to receive project returns unless the borrower is current on TIFIA interest payments. TIFIA interest rates are equivalent to Treasury rates.
Depending on market conditions, these rates are often lower than what most borrowers can obtain in the private markets. Unlike private commercial loans with variable rate debt, TIFIA interest rates are fixed.
Overall, borrowers benefit from improved access to capital markets and potentially achieve earlier completion of large-scale, capital intensive projects that otherwise might be delayed or not built at all because of their size and complexity and the market's uncertainty over the timing of revenues. Chapter 2 of the Build America Bureau's Programs Guideprovides further detail on TIFIA credit instruments and other funding issues.
