Dutchess County's Poor-condition bridges carry 369,737 vehicle crossings a day

That is 16.2% of the county's reported daily bridge traffic on 16.5% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 6,847 crossings a day against 6,687 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.

59.3% of Dutchess County's bridges have passed the 50-year mark

197 of the 332 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 22.6% 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 7.2% of the county's Poor-condition bridge traffic

RTE 9 over RAILROAD PLAZA, built 1966, carries 26,742 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 55-bridge count understates how much of the daily burden sits on a single crossing.
