Cayuga County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Cayuga County ranks #58 of 62 New York counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 16.9%). Cayuga County, New York contains 148 public highway bridges. Roughly 36.5% are rated “Good,” 46.6% “Fair,” and 16.9% “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.

Cayuga County's Poor-condition bridges carry 46,709 vehicle crossings a day

That is 10.9% of the county's reported daily bridge traffic on 17% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 1,868 crossings a day against 3,489 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 147 of 148 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

50.7% of Cayuga County's bridges have passed the 50-year mark

75 of the 148 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 36.5% 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 65.3% of the county's Poor-condition bridge traffic

RTE I90 over CRANE BROOK, built 1953, carries 30,507 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.
