The Michigan Transportation Asset Management Council (TAMC) is proud to present Michigan’s 2021 Roads and Bridges Annual Report. The report was distributed to the Michigan Legislature, State Transportation Commission and Michigan Infrastructure Council (MIC) as directed under Michigan Compiled Law (MCL) 247.659a(9).
“The 2021 report highlights the largest quantity of road condition data collected and the highest percent of roads rated in good condition since 2005," stated TAMC Chair Joanna I. Johnson.
The 2021 condition data for Michigan’s federal-aid eligible paved roads has made progress with
In 2020, estimated breakdown was
This improvement in road surface condition may be due in part to several factors including a mix of fixes of road surface treatments and increased revenue. The reasons for this improvement will be analyzed further and better understood as the 2021 project data becomes available.
Michigan’s bridges declined in condition in 2021 with
The Severe category measures the criticality and is 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 2021 Roads and Bridges Annual Report can be viewed, along with previous annual reports, at www.Michigan.gov/TAMC. The extensive 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. “We know the data provides a valuable resource to assist in decision-making and asset management planning,” stated Chair Johnson.
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.
