Richmond County, New York contains 164 public highway bridges. Roughly 30.5% are rated “Good,” 67.7% “Fair,” and 1.8% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale.

Richmond County's Poor-condition bridges carry 79,652 vehicle crossings a day

That is 1.6% of the county's reported daily bridge traffic on 2.1% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 26,551 crossings a day against 38,800 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.

74.4% of Richmond County's bridges have passed the 50-year mark

122 of the 164 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 30.5% 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 71.8% of the county's Poor-condition bridge traffic

RTE 440 over ARTHUR KILL ROAD, built 1977, carries 57,220 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 3-bridge count understates how much of the daily burden sits on a single crossing.
