Barry County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Barry County ranks #82 of 83 Michigan counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 24.6%). Barry County, Michigan contains 69 public highway bridges. Roughly 26.1% are rated “Good,” 49.3% “Fair,” and 24.6% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale. It is a condition category, not a live safety or closure decision.
Responsible agencies inspect covered bridges on risk-based intervals under current NBIS rules and submit inventory data to FHWA annually. The list below shows every NBI-tracked bridge in the county. Use the “Sort by” controls to change the ordering, and click any row for its reported inspection date, traffic count, and condition fields.

Barry County's Poor-condition bridges carry 8,336 vehicle crossings a day
That is 7.7% of the county's reported daily bridge traffic on 24.6% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 490 crossings a day against 2,498 for a Good-condition one. A Poor rating is a condition category, not a closure or a live safety judgement; it means the lowest applicable component rating is 4 or below.

60.9% of Barry County's bridges have passed the 50-year mark
42 of the 69 bridges with a recorded construction year were built in 1974 or earlier. Age alone is not a defect: a well-maintained older bridge can rate Good, and 26.1% of this county's inventory does. Even so, this older cohort is the population from which future Poor ratings are drawn, which is why the age profile below matters alongside the condition split above.
Cutoff derives from the 2024 release year minus a 50-year design life. Source: FHWA National Bridge Inventory, 2024 release.
One structure carries 44% of the county's Poor-condition bridge traffic
M-66 over QUAKER BROOK, built 1940, carries 3,666 vehicles a day, the most of any Poor-rated structure here. The county's Poor-condition exposure is concentrated rather than evenly spread, so the 17-bridge count understates how much of the daily burden sits on a single crossing.
