Whether advertising on the requesting funding assistance for projects to be placed on a state letting or a local letting, IDOT is responsible for directing federal, state, and local funding to maintain, enhance, and expand Illinois’ publicly owned, open to the public airports through its Proposed Airport Improvement Program. Within the Proposed Airport Improvement Program process, the airport sponsor requests financial assistance for airport improvement projects over the next three to five federal fiscal years through the Transportation Improvement Proposal (TIP) request process. In order to meet eligibility requirements, all projects must first be formally requested through the TIP process annually.

Getting Started

The process begins with meetings with IDOT’s Division of Aeronautics representatives (meeting dates are communicated through mass emails) where programming guidance and aid in preparing for submittal packets is discussed. Meetings tend to be scheduled in the fall on an annual basis.

Submit Potential Projects

Airport projects are selected from submittals by the airport sponsors and evaluated based on federal priority rating and need on an annual basis. Due to eligibility, justification, project readiness and funding limitations, not all projects requested in the TIP are included in the three-year Proposed Airport Improvement Programs. The Proposed Airport Improvement Program does not reflect all of the airport needs or deficiencies but simply reflects those projects identified by the airport sponsor as desiring federal and or state financial assistance.


Final TIP Submittals Due: December 15, 2023
Incomplete submittals will not be processed and will be rejected. A completed submittal consists of the following materials.
