Rebuild Illinois Airport Capital Improvement Program

Program Purpose

The Rebuild Illinois Airport Capital Improvement Program (ACIP) provides competitive grants for the planning, construction, reconstruction, extension, development, and improvement of public-use airports that are included in the Illinois Aviation System Plan (IASP). ACIP grants augment the continual Federal Airport Improvement Program (AIP), and other state aviation programs, where funding limitations and constraints prevent otherwise justified projects from being completed.

In the Spring of 2019, Rebuild Illinois appropriated the sum of $144 million to the Illinois Department of Transportation (IDOT) for such purposes, in accordance with the Illinois Aeronautics Act and other applicable state statutes. Considering demand for funding a growing backlog of justified improvements to the Illinois Aviation System (IAS), and the complexity inherent in the planning, design, letting and construction process for airports, IDOT will utilize this 6-year capital bill appropriation to establish no greater than a 4-year ACIP from FY 2021 – FY 2025.

Additionally, Rebuild Illinois appropriated the sum of $6 million to IDOT for a grant to Lewis University Airport for costs associated with erecting an air traffic control tower. This project is expected to follow the same program timeframe, although consideration must be given to Federal Aviation Administration (FAA) coordination and requirements.


$94 million is available for the Rebuild Illinois Airport Capital Improvement Program, It is anticipated funds will be programmed over state fiscal years FY 2022 – FY 2025.


Eligible applicants are public-use public-owned airports in Illinois.

Furthermore, to be eligible for a grant, an airport must be included within the IASP. This listing can be found in the resources below.

Recipients of grants are referred to as "sponsors." Sponsors must be legally, financially, and otherwise able to carry out state and federal assurances and obligations contained in the project application and grant agreement, including the ability to meet and comply with the Grant Accountability and Transparency Act (GATA).
