Essex County, New York contains 256 public highway bridges. Roughly 48.4% are rated “Good,” 44.5% “Fair,” and 7% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale.

Essex County's Poor-condition bridges carry 24,846 vehicle crossings a day

That is 6.1% of the county's reported daily bridge traffic on 7.3% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 1,380 crossings a day against 1,664 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.

43.4% of Essex County's bridges have passed the 50-year mark

111 of the 256 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 48.4% 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

RIVER STREET EXT over OUTLET BROOK, built 1984, carries 6,437 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 18-bridge count understates how much of the daily burden sits on a single crossing.
