Oneida County, New York contains 496 public highway bridges. Roughly 46.2% are rated “Good,” 42.3% “Fair,” and 11.5% “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.

Oneida County's Poor-condition bridges carry 141,180 vehicle crossings a day

That is 6.1% of the county's reported daily bridge traffic on 11.1% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 2,614 crossings a day against 5,149 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.

50.8% of Oneida County's bridges have passed the 50-year mark

252 of the 496 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 46.2% 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 17.9% of the county's Poor-condition bridge traffic

RTE I90 over NYO&W RR (ABAND), built 1954, carries 25,281 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 57-bridge count understates how much of the daily burden sits on a single crossing.
