Status: We are currently accepting applications.

Below are the types of SIB loan applications that we accept. Please fill out all items in the SIB loan application. If you have questions about anything on the application, please call (512) 463-9958.

First-Come, First-Served Application

A SIB loan application under $10 million for work necessary for a TxDOT project is exempt from the program call, and each application will be reviewed on a first-come, first-served basis. One Commission approval will be required after final loan terms are negotiated.

Program Call Application

A SIB loan application for a non-TxDOT project or SIB loan over $10 million will be prioritized against other applications in a Program Call. Two Commission approvals will be required:

  • Prioritization and preliminary approval of complete applications
  • Final approval of loan terms after negotiations are completed

For a list of prioritization considerations, please see §6.32(c)(1) of the SIB Rules.

Interest Rate Information

General Information

The SIB uses the Municipal Market Index (MMD) to set interest rates. This index is updated weekly.

  • Rates are set at the time we receive a completed application.
    • The rate will be reset if the loan does not go before the Texas Transportation Commission within 12 months.
  • Rate is determined based on the current credit rating of the borrower and the term of the loan
    • Ex. Higher rating = lower rate; Shorter term = lower rate.
  • Credit rating not required to borrow.
  • Fixed rate for the life of the loan.

Please contact us to inquire about current rates.

Current Interest Rate Discounts


  • No interest assessed until the end of 2022
  • Rate for the rest of the term is the normal set rate.
  • Available for all applications received.
