Holt County, Missouri contains 167 public highway bridges. Roughly 38.3% are rated “Good,” 46.7% “Fair,” and 15% “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.

Holt County's Poor-condition bridges carry 15,454 vehicle crossings a day

That is 6.3% of the county's reported daily bridge traffic on 15% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 618 crossings a day against 1,009 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.

Computed over the 167 of 167 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

55.1% of Holt County's bridges have passed the 50-year mark

92 of the 167 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 38.3% 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 54.2% of the county's Poor-condition bridge traffic

IS 29 N over LIT TARKIO CR, built 1972, carries 8,371 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 25-bridge count understates how much of the daily burden sits on a single crossing.
