The Transportation Improvement Program (TIP) is a federally required, four-year plan for tracking and funding certain transportation improvements across the MPO’s planning area. The 2026-2029 Transportation Improvement Program is the currently approved TIP for the Central Indiana planning area. The IMPO’s online TIP database, MiTIP, provides up-to-date project information.

The TIP tracks federal transportation investments in Central Indiana between state fiscal years 2026-2029. It also includes projects deemed “regionally significant” for air quality during this period regardless of funding source and any projects funded with any MPO-managed funds. The TIP is programmed based on forecasts provided by INDOT from the current Federal transportation bill. Revenue projections programmed between 2026 and 2029 exceed the projected expenditures for transportation improvement projects to ensure the TIP is fiscally constrained. Projects are developed in partnership with the Indiana Department of Transportation (INDOT), regional transit providers, local governments, and with input from residents. The IMPO also collaborates with INDOT to align with the State Transportation Improvement Program (STIP).

The TIP tracks federally funded and air quality significant transportation projects in Central Indiana. Developed with INDOT, local agencies, and public input, it aligns with the State Transportation Improvement Program (STIP). The TIP evolves as project timelines and costs change. Major changes in cost or scope require a “TIP amendment” approved by the IMPO Transportation Policy Committee, with formal amendments occurring six times a year. After approval, amendments move through INDOT’s STIP and FHWA. Projects impacting air quality require additional steps. Minor changes can be approved administratively.

Each year, the IMPO receives $70–80 million in federal transportation funding from the Federal Highway Administration (FHWA), passed through the Indiana Department of Transportation (INDOT). This funding is allocated to local public agencies (such as cities, towns, counties, and transit organizations) for transportation projects including roads, bridges, trails, and transit.

To distribute these funds, the IMPO holds an annual call for projects. Applicants must submit data-driven proposals and commit to a local funding match. Typically, the IMPO covers up to 80% of construction and construction engineering costs, while the local agency is responsible for the remaining 20%, as well as 100% of preliminary engineering, right-of-way, and other project expenses.

Projects are scored and ranked based on approved selection criteria and alignment with the Metropolitan Transportation Plan (MTP) goals. A recommended funding list is then submitted to the Transportation Policy Committee, which includes representatives from member agencies, for final approval. Once approved, the projects are amended into the TIP. Through the Federal Funds Exchange (FFE), the IMPO also partners with the State of Indiana to substitute state funds for federal funds in most grant programs.

Policies, schedules, calculators, forms, and FAQ.

In August of 2020, the Indianapolis Metropolitan Planning Organization (IMPO) signed an agreement with the Indiana Department of Transportation (INDOT) to exchange the IMPO’s annual allocation of Federal transportation program funds for State funds to fund regionally significant transportation projects in the Indianapolis Regional Transportation Improvement Program (TIP). The policies and procedures are the result of collaboration between the IMPO, the Transportation Technical and Policy Committees, INDOT, and feedback from local public agencies. Local agencies may also wish to review a short overview presentation or the full training recording.

Recent amendments to the TIP.

Formal amendments are significant changes to the TIP that require an opportunity for public review and comment and require approval by the IMPO’s Transportation Policy Committee at a public hearing. This often includes adding new projects, deleting projects, or significant cost changes. For more information about a project visit the IMPO’s online TIP database, MiTIP, and enter the project DES number in the Advanced Search tab.

You are invited to participate in our regional planning process. Public comments are encouraged to be submitted in advance by email to info@indympo.org, by mail to 200 East Washington Street, Suite 2322, Indianapolis, IN 46204, or by phone to our voicemail line at 317-327-8601. Public comment opportunities will also be available in person during any listed public hearings.

Modifications are minor changes to projects or the TIP that do not require the IMPO’s Transportation Policy Committee’s approval or public review. These include but are not limited to general editorial corrections; changes to projects that do not involve a significant change in the use of IMPO funds such as minor cost increases, moving fiscal years within the active years of the current TIP, minor scope changes that do not change the overall project impact or transportation conformity, or moving projects from the previous TIP into the current TIP. Modifications from the most recent quarter are below. For more information about what types of changes result in a TIP amendment review the TIP Amendment and Modification Policies. Visit MiTIP for recent modifications.

Frequently asked questions about the TIP including submitting applications

In accordance with Federal requirements, the MPO publishes its “Annual List of Obligated Projects” (ALOP) based on information provided by INDOT. The purpose of the report is to provide to the public, as well as State and local officials, information regarding federal spending on transportation projects within the Indianapolis region, along with a progress report and disclosure of project delivery occurring over a shorter planning period of only one year.
