What is the TIP?

What is the Transportation Improvement Program?

Our transportation options and quality of infrastructure impact more than just mobility. They influence how we attract talent, create community places, drive economic development, and prioritize connectivity and accessibility for all who live, work, and play in the Greater Lansing region.


This is why the projects included in our Transportation Improvement Program, or TIP for short, represent more than just an investment into our transportation system – they are an investment into our region’s prosperity and success.


The TIP is the region’s short-range capital improvements program for roads, bicycle and pedestrian pathways, public transit, and other transportation enhancements in Greater Lansing's tri-county region. It includes a list of the federally funded projects planned within Clinton, Eaton, and Ingham counties over the next four years, as well as background information and statutory regulations that guide regional transportation planning across the country.


The TIP is a living document - changes to projects, including adding new ones, adjusting timelines for construction, removing projects, and changings costs and other information are made throughout the year at meetings of our technical advisory committee and Board of Commissioners. Previous amendments may be viewed in past meeting materials.

FY 2023-2026 TIP

FY 2023-2026 Transportation Improvement Program

Tri-County's Board of Commissioners adopted the Transportation Improvement Program (TIP) for fiscal years 2023 through 2026 on May 25, 2022. Our fiscal year 2023-2026 TIP, which runs from October 2022 through September 2026, includes a variety of projects to improve our roads, non-motorized facilities, public transit services and buses, operations, system safety, and bridges. This TIP includes over $500 million of investment into our region's transportation infrastructure and systems!

The TIP is a living planning document and revisions to projects are made throughout the year. Significant revisions, called amendments, are listed below for this TIP cycle. These are shared with the CARTS Technical Committee, along with any minor administrative modifications made to projects, and approved by the Board.
