    • Congestion Mitigation and Air Quality (CMAQ)

    Metadata Updated: December 7, 2023

    All 50 states and the District of Columbia submit annual reports of their CMAQ project obligations in March of every year. The FHWA uses these yearly submissions to maintain an active database of CMAQ investments, trends within the program, and other anecdotal information focusing on the program's performance. This database of CMAQ Project information has always been reserved for internal use by authorized FHWA personnel for Congressional reporting and made available to state DOTs and MPOs on a limited basis.
