Truck Access Route Program (TARP)

The purpose of TARP is to help local governments upgrade roads to accommodate 80,000 pound truck loads.

TARP Fall Solicitation

Every fall IDOT solicits local projects that can be constructed during the upcoming fiscal year. We encourage you to submit your inquiries and requests for assistance to the district Local Roads and Streets office that serves your county. This program will provide $45,000 per lane mile and $22,000 per eligible intersection for selected projects. The state participation will not exceed 50 percent of the total construction costs or $900,000, whichever is less.

Submitting an Application

Please contact your district Local Roads and Streets office for details on how to apply for TARP.
The following information is needed for all TARP applications:

  • A general description of the project
  • A location map
  • The limits of the project
  • Total mileage, including lane miles
  • Number of trucks per day
  • Intersections with designated truck routes only
