Cattaraugus County's Poor-condition bridges carry 44,292 vehicle crossings a day

That is 4.3% of the county's reported daily bridge traffic on 6% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 1,527 crossings a day against 2,257 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 480 of 484 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

36.2% of Cattaraugus County's bridges have passed the 50-year mark

175 of the 484 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 55.4% 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 25.9% of the county's Poor-condition bridge traffic

RTE I86 over GODFREY HLLOW BRK, built 1972, carries 11,480 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 30-bridge count understates how much of the daily burden sits on a single crossing.
