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. You can learn more about the federal CMAQ funding program here.

About STBG

The Surface Transportation Block Grant Program (STBG) is the most flexible type of federal transportation funding and can be used for a wide range of transportation projects, planning, and programs. You can learn more about the federal STBG funding program here.
