Greene County's Poor-condition bridges carry 78,240 vehicle crossings a day

That is 11.7% of the county's reported daily bridge traffic on 9.8% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 3,556 crossings a day against 1,368 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.

45.4% of Greene County's bridges have passed the 50-year mark

103 of the 227 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 36.6% 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 43% of the county's Poor-condition bridge traffic

RTE I87 over CAUTERSKILL ROAD KAATER, built 1955, carries 33,622 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 22-bridge count understates how much of the daily burden sits on a single crossing.
