Purpose of the Program

The purpose of TARP is to assist local governments in upgrading roads to accommodate 80,000-pound trucks and to enhance local transportation and economic development. Applications must include a general description of the project and a map showing project site; total mileage, including lane miles and number of intersections; description of truck generators and number of trucks per day, total cost of the project along with the local funding share; and anticipated letting date.

Who is Eligible

Eligible applicants are local governments that need assistance upgrading roads to accommodate 80,000 pound trucks. Projects must connect to a truck route and end at another truck route or truck generator.

Application Process

IDOT annually solicits local projects that can be constructed during the upcoming fiscal year. Applicants should initiate inquiries and requests for assistance at the appropriate District office for their county. The following information is needed for applications: a general description of the project and a location map, an engineer’s cost estimate of the improvement, and the amount and source of local matching funds.

Availability of Funds

IDOT will provide up to $45,000 per lane mile and $22,000 per intersection or up to 50 percent of the total project cost, whichever is less.  When used in conjunction with an Economic Development Program project, TARP funds are capped at $900,000 per project.

How Funds are to be used

Funds are to be used to upgrade truck routes to provide access to points of loading and unloading, and to facilities for food, fuel, truck repair, and driver rest.
