CMAQ and STBG Programs

About CMAQ

The Congestion Mitigation and Air Quality Improvement Program (CMAQ), is a federal-aid highway program that provides funds for transportation projects or programs that will contribute to meeting the requirements of the Clean Air Act.  CMAQ funds generally cannot be used for projects that result in the construction of new capacity for single-occupancy vehicles.
