Congestion Mitigation and Air Quality Improvement program

The Congestion Mitigation and Air Quality (CMAQ) Improvement program​ encourages transportation projects that improve air quality. It includes efforts to enhance public transit, bicycle/pedestrian facilities, ridesharing programs and facilities, and technologies that improve traffic flow and vehicle emissions.

CMAQ funds are only available in these southeastern and northeastern Wisconsin non-attainment and maintenance counties: Milwaukee, Racine, Kenosha, Waukesha, Washington, Ozaukee, Walworth, Sheboygan, Kewaunee, Manitowoc and Door. The department solicits applications every other year.

CMAQ funding was continued pursuant to Moving Ahead for Progress in the 21st Century (MAP-21), the federal transportation act that was signed into law on July 6, 2012. MAP-21 provisions took effect on October 1, 2012. Generally, projects eligible for CMAQ funding pursuant to SAFETEA-LU remain eligible for funding under current legislation. MAP-21 continues to emphasize cost-effective projects, and legislation prioritizes certain projects such as those that reduce particulate matter emissions in areas of nonattainment for this criteria pollutant.
