Transportation Improvement Program (TIP)
The TIP is a four year schedule of transportation projects selected as priorities for funding by cities, villages, county road commissions, transit agencies, and the Michigan Department of Transportation. The TIP is an implementation tool of the Regional Transportation Plan (RTP). Projects in the FY 2023-2026 TIP must advance the goals and policies adopted in the RTP. There are five Amendment periods per year to process major changes to the TIP, while it is also regularly updated with minor changes referred to as administrative modifications.
General Program Accounts (GPAs) are groupings of similar routine transportation projects within the TIP as permitted in Federal regulation 23 CFR 450.324 (f) under 23 CFR 771.117(c) and (d) and/or 40 CFR part 93. Projects not required to be programmed as Line-Item projects are programmed under an appropriate GPA by jurisdiction and type, such as Local Road, Trunkline Road, or Transit Capital. When the total cost of all the projects within a GPA equals or exceeds 125% of the GPA’s current federally approved limit, an amendment is required to reflect this change in size.
FY 2026-2029 TIP Development
Southeast Michigan is transitioning from the close of the current 2023-2026 TIP to the beginning of the new 2026-2029 TIP. FY 2026 projects adopted in the 2023-2026 TIP will also be amended into the 2026-2029 TIP for consistency and to ensure timely delivery of projects. The proposed FY 2026-2029 TIP includes a variety of projects designed to address regional transportation policies and priorities – pavement, safety, bridge, operations, transit (capital and operations), capacity, and pedestrian and bike mobility projects. These projects are proposed with consideration to meeting regional and statewide transportation performance targets. Projects in this list were either rolled over from FY 2026, submitted during the 2024 call for projects, or included in the MDOT 5-Year Plan. It is customary for additional projects to be submitted to the TIP via future administrative modifications or amendments.
The FY 26-29 TIP must undergo the following reviews:
- Public Review: 3/25/25-4/25/25 [complete]
- Transportation Coordinating Council (TCC): 4/17/25 [complete]
- Executive Committee: 4/25/25 [complete]
- MDOT, FHWA and FTA (Summer 2025)
The FY 26-29 TIP is anticipated to take effect 10/1/2025.
