April 28, 2021 – The Michigan Transportation Asset Management Council (TAMC) published Michigan’s 2020 Roads and Bridges Annual Report and distributed it to the Michigan Legislature, State Transportation Commission and Michigan Infrastructure Council (MIC) as directed under Michigan Compiled Law (MCL) 247.659a(16).

“The 2020 report reveals the on-going challenges of maintaining Michigan’s federal aid eligible roads as the deterioration cycle of roads unfortunately shows a continued trend of Poor condition", stated TAMC Chair Joanna I. Johnson. The 2020 condition for Michigan’s Federal Aid eligible paved roads has made some progress with:

 22% Good

 36% Fair, and

 42% in Poor condition.

In 2019, the breakdown was 21% Good, 40% Fair, and 39% were in Poor condition. The 2020 condition reporting for Michigan’s Federal Aid eligible road network is estimated from projections of 2018 and 2019 data sets. Looking back at the 2015 condition data 16% Good, 45% Fair, and 39% were in Poor condition.

Michigan’s bridges declined in condition in 2020 with:

 36% Good,

 53% Fair,

 7% Poor, and 4% falling into “Severe” condition.

In 2019, the distribution was 38% Good, 51% Fair, 7% Poor and 4% Severe. In 2015, the distribution was 43% Good, 46% Fair, and 11% Poor. The Severe category was added into TAMC reporting in 2019 as a measure of criticality and a warning that these structures are in jeopardy for closure due to structural concerns that could pose a threat to traffic. “We continue to lose progress with these valuable assets, especially as we look at neighboring Great Lake States”, stated Chair Johnson.

Michigan’s 2020 Roads and Bridges Annual Report can be viewed, along with previous annual reports, at www.Michigan.gov/TAMC. The data for this report was achieved through a cooperative effort of individuals from the Michigan Department of Transportation (MDOT), city, village, and county road agencies, in coordination with regional planning agencies, and metropolitan planning organizations.

The TAMC includes representatives from MDOT, Michigan Municipal League (MML), Michigan Association of Counties (MAC), Michigan Townships Association (MTA), Michigan Association of Regions (MAR), Michigan Transportation Planning Association (MTPA), the County Road Association of Michigan (CRA), and the Michigan Department of Technology, Management and Budget-Center for Shared Solutions (MCSS). Transportation asset management is a process of managing public assets, such as roads and bridges, based on the long-range condition of the entire transportation system. The TAMC, created in 2002 by the Michigan Legislature, promotes the concept that the transportation system is unified, rather than separated by jurisdictional ownership.
