Transportation Improvement Program

Among other tasks, the IMPO tracks and distributes funds through a program known as the Indianapolis Regional Transportation Improvement Program (IRTIP), or “TIP” for short. The TIP is a four-year plan for Central Indiana infrastructure. Depending on the type of project, the TIP tracks, schedules, and funds projects in Central Indiana based on regional priorities and cooperative input from communities throughout the area. The IMPO 2024-2027 TIP document provides vital information on project funding, federal programs, policies, and public involvement.

The TIP is a four-year schedule of transportation projects proposed by government and transportation agencies in the Indianapolis Metropolitan Planning Area using certain funds. The TIP changes over time as projects get delayed, advance quicker than anticipated, and costs change. These changes are called TIP amendments. The TIP is formally amended six times a year to reflect amendments and to add new projects as they receive funding through continuing calls for projects from the Indianapolis Metropolitan Planning Organization (IMPO), Indiana Department of Transportation (INDOT), or the Federal Transit Administration (FTA). Large or significant amendments, often an increase in costs more than $100,000, require the approval of the IMPO Transportation Policy Committee.

The IMPO's online database known as "MiTIP" allows the public to view programmed transportation projects contained in the TIP online. MiTIP represents the most current version of the TIP at any given time. Information from the TIP database may also be provided in other formats and languages for viewing online or in-person at our offices. For more information contact staff at or 317-227-5108 or visit our offices at 200 East Washington Street, Suite 2322, Indianapolis, IN 46204.

Project Funding and the Call for Projects

The IMPO receives an annual allocation of funding from INDOT to support transportation projects within the Metropolitan Planning Area (MPA). A legislatively approved formula is used by the Federal Highway Administration (FHWA) to distribute funding to each state which then allocates these funds to MPOs. Each year the IMPO goes through a competitive process to determine what projects receive this funding. To select projects to receive the IMPO’s funding, the IMPO issues an annual “call-for-projects”.

During the call-for-projects local public agencies (typically cities, towns, counties, and transit organizations) choose projects to submit for consideration by completing a data-driven application and committing to locally fund a portion of the project cost. The IMPO then selects projects for funding based on the funding goals of the Metropolitan Transportation Plan (MTP) as adopted by the IMPO’s Transportation Policy Committee, federal eligibility requirements, and on their rank after the scoring process based on the IMPO's scoring criteria.

More Information about the TIP and TIP Amendments

Below you will find information about the federal legislation that enables the TIP, current and proposed amendments to the TIP, information on the Federal Funds Exchange Program, and other useful information.

Federal Fund Exchange Program

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 TIP documents the Federally funded transportation improvements proposed for the Indianapolis Metropolitan Planning Area (MPA) over a four-year period. This program is known as the Federal Funds Exchange Program and its policies will affect all future project calls for the IRTIP.

Local public agencies may learn more about the Federal Funds Exchange Program by viewing the program’s guidance document. The guidance document outlines the policies and procedures required for participation in the program in relation to the ITRIP call-for-projects including our quarterly tracking policy. 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.

LPAs may also wish to review a short overview presentation of the guidance document. Recordings of the guidance document training held in August 2021 are also available. LPAs may view the full training recording or view sections of the training including a program overview, application requirements, project costs, project management, and the Q&A session.

Coronavirus, Response, and Relief Supplemental Appropriations Act (CRRSAA)

On February 24, 2021 the U.S. Department of Transportation issued implementation guidance on the $9.8 billion in supplemental Highway Infrastructure Program (HIP) funds apportioned to state departments of transportation by the Coronavirus, Response, and Relief Supplemental Appropriations Act (CRRSAA). The legislation provided additional funds through the Federal Highway Administration (FHWA) to address the significant impacts of COVID-19 on the nation’s transportation systems.

The State of Indiana was allocated $236,385,835 in CRRSAA funds and the Indianapolis MPO’s urbanized area was allocated $13,398,652 of those funds. These funds are available for obligation immediately and are available for obligation until September 30, 2024.

On June 2, 2021 the IMPO Transportation Policy Committee adopted Resolution #21-IMPO-011 directing the MPO to apply the region’s allocation of CRRSAA funds to existing infrastructure projects scheduled for State fiscal year 2022. State fiscal year 2022 is heavily programmed with transportation projects and, therefore, this application of CRRSAA funds will allow more projects to be funded without delays. This application of CRRSAA funds is also intended to meet INDOT’s guidelines and promptly obligate funds to construction. IMPO staff will review funding availability in fiscal year 2022 after the completion of quarterly project tracking and project lettings. Staff will be able to provide a list of projects that will use CRRSAA funds once that is known.

Infrastructure Investment and Jobs Act (IIJA)

On November 15, 2021, the Infrastructure Investment and Jobs Act (IIJA) was signed into law. The Act reauthorizes several surface transportation programs for FY2023-FY2026 including the federal-aid highway program, transit programs, and highway-safety programs. The Act includes increased funding for existing programs including the core STBG, CMAQ, HSIP, and TAP federal transportation funding programs managed through the Transportation Improvement Program. The Act also expands project eligibility for some funding sources and includes new funding sources for a variety of project types that may be available to local public agencies. The IMPO will work with the IMPO Technical, Policy, and Executive Committees to determine the best use of the increased funding available. The IMPO will also monitor additional funding opportunities created by the Act and communicate opportunities to local public agencies.

Proposed TIP Amendments

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 what types of changes result in a TIP amendment review the Federal Funds Exchange Policy. For more information about a project visit our database and enter the project DES number in the Advanced Search tab.

The proposed Q4S 2023 TIP amendments are available for public review and comment between November 25 and December 5. A public hearing will take place on the amendments on December 6 at 9am at 9503 E. 33rd St. Indianapolis IN. To submit comments in advance of the meeting please email or send us mail to our offices at at 200 East Washington Street, Suite 2322, Indianapolis, IN 46204. You may also visit the office in-person to review and provide comments on documents. We suggest calling us at 317.327.8601 to set up a time to visit.

Annual List of Obligated Projects (ALOP)

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.

Administrative TIP Modifications

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 last 30 days are below. For more information about what types of changes result in a TIP amendment review the Federal Funds Exchange Policy.
