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 required by law.
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
- 4% Severe
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.
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.
