Posted on May 4, 2023 by Matt Bach

The Michigan Transportation Asset Management Council has released Michigan’s 2022 Roads & Bridges Annual Report. The Council asked the Michigan Municipal League to share the report with our members.

Here is the press release with all the details:

The Michigan Transportation Asset Management Council (TAMC) is proud to present Michigan’s 2022 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 report highlights Michigan leading the nation in local asset management practices nationwide and reflects on TAMC’s 20-year journey since creation in 2002. Added highlights in this report includes information on the first submission cycle of local road agencies reporting for Transportation Asset Management Plans (TAMPs) based on PA 325 of 2018, gravel roads data, Act 51 investment reporting, and traffic signal inventory survey.

Michigan’s 2022 Federal Aid eligible paved roads maintained the gains made in 2021:

– 25% Good
– 42% Fair, and
– 33% in Poor condition.

Over 290 road agencies collected road condition on 90% of their federal-aid road network. Two milestones of highest accuracy of PASER road condition data and most non-federal-aid lane miles of road condition collected in 20 years. This is vital to quality data and for further inventory and data collection of the complete road network in the State.

Michigan’s 2022 bridges declined in condition, continuing a trend since 2014:
– 34% Good,
– 54% Fair,
– 8% Poor, and 4% falling into “Severe” condition.

The Severe category is a warning that these structures are in jeopardy for closure due to structural concerns that could pose a threat to traffic. Local bridges closed due to condition increased by 15% in 2022.

Michigan’s 2022 Roads and Bridges Annual Report can be viewed, along with previous annual reports, dashboards, and interactive maps at 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.
