Congestion Mitigation & Air Quality

The CMAQ program funds transportation projects or programs that will contribute to the attainment or maintenance of the National Ambient Air Quality Standards (NAAQS) for ozone (NOx and VOC), carbon monoxide (CO), or particulate matter (PM 2.5).

The CMAQ program supports two important goals: Improving air quality and relieving congestion.

Call for Projects

The purpose of the Call for Projects (CFP) is to identify, select, and approve projects that align with MDOT's goals, policies, and strategic plan. Submit CMAQ project applications according to the CFP instructions.

Projects should be submitted via JobNet through MILogin for Third Party.

Note: CMAQ is not a grant program. The role of the CMAQ CFP Committee is to determine the Federal Aid eligibility for CMAQ funding. If a project is deemed eligible by the CMAQ CFP Committee, this is not a final approval of the project. Project applicants must also work with MDOT regions, TSCs, LAP, and all other appropriate agencies responsible in issuing approvals and permits. It is not uncommon for a project to require modifications after an eligibility determination based on the feedback of these entities.
