Transportation Revolving Loan Fund (TRLF)

The federal government established a State Infrastructure Bank (SIB) program in 1995 through the National Highway System Designation Act. A SIB is a state or multi-state fund that can be used by eligible borrowers to finance eligible transportation projects.

Minnesota's SIB, known as the Transportation Revolving Loan Fund (TRLF), was established in 1997. The TRLF operates much like a commercial bank providing low interest loans to cities, counties, and other governmental entities for eligible transportation projects. When the loans are repaid, the funds are returned to the TRLF and used to finance additional transportation projects. 

The TRLF is an innovative finance tool that can be used to finance transportation projects that may not get financed through traditional transportation funding methods. The TRLF's benefits include:

  • Faster project completion resulting in cost-savings and improved transportation systems.
  • A variety of low-cost financing options.
  • The ability to fund additional projects as loans are repaid.
  • The attraction of new types of dollars for transportation use.
  • The generation of additional dollars for transportation purposes through leveraging.
