Beltrami County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Beltrami County ranks #36 of 87 Minnesota counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 3%). Beltrami County, Minnesota contains 101 public highway bridges. Roughly 63.4% are rated “Good,” 33.7% “Fair,” and 3% “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.

Beltrami County's Poor-condition bridges carry 1,424 vehicle crossings a day
That is 1% of the county's reported daily bridge traffic on 3% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 475 crossings a day against 874 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.

13.9% of Beltrami County's bridges have passed the 50-year mark
14 of the 101 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 63.4% 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 55.6% of the county's Poor-condition bridge traffic
MN 72 over TAMARAC RIVER, built 1962, carries 792 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 3-bridge count understates how much of the daily burden sits on a single crossing.
