Ulster County, New York contains 392 public highway bridges. Roughly 21.7% are rated “Good,” 57.4% “Fair,” and 20.9% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale.

Ulster County's Poor-condition bridges carry 204,453 vehicle crossings a day

That is 12.9% of the county's reported daily bridge traffic on 20.6% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 2,588 crossings a day against 4,217 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.

49.7% of Ulster County's bridges have passed the 50-year mark

195 of the 392 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 21.7% 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 17.5% of the county's Poor-condition bridge traffic

RTE I87 over RTE 213 WALLKILL RIVER, built 1955, carries 35,755 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 82-bridge count understates how much of the daily burden sits on a single crossing.
