County profile · official public datasets
496 public highway bridges tracked in the FHWA National Bridge Inventory: 46.2% rated Good, 42.3% Fair, 11.5% Poor.
The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Oneida County posts a higher-than-median Poor-condition share among rated counties in the state across mid-size county bridge inventory.
Poor is an FHWA condition category from the lowest applicable component rating (4 or below), not a live crossing-safety or closure decision. Rankings cover counties with at least five public highway bridges.
According to the Federal Highway Administration's 2024 National Bridge Inventory, Oneida County ranks #43 of 62 New York counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 11.5%). 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.

Share of 496 NBI-tracked bridges by lowest applicable component rating.
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.

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.
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.

What this shows Construction peaked in the 1990s, when 70 of the county's bridges still in the inventory were built, which is 14.1% of those with a recorded year. That cohort is now 25 to 34 years old in the 2024 inventory. Its average build year (1972) matches the New York average (1972).
The 5 New York counties nearest Oneida County in number of bridges, with their condition splits. Its 11.5% Poor share is the 5th-lowest of these 6. Its average build year of 1972 against a peer-group mean of 1974 is in line with the group.
