Transportation & Mobility

About Our Transportation Program

The Tri-County Regional Planning Commission was designated by the Governor as the Metropolitan Planning Organization (MPO) in 1973, responsible for fulfilling all federally required transportation planning requirements in the Lansing-East Lansing Metropolitan area throughout Clinton, Eaton, and Ingham counties (Michigan's tri-county region).

We ensure that existing and future expenditures for transportation planning projects and programs are based on a continuing, cooperative, and comprehensive (3-C) planning process. Federal funding for transportation projects and programs in the tri-county area are channeled through the Commission. In accordance with federal regulations, Tri-County is required to carry out metropolitan transportation planning in cooperation with the State and operators of publicly owned transit services.

Transportation Improvement Program

Our 4-year capital improvements program includes more than $680 million of transportation investment in the region.
