Schenectady County's Poor-condition bridges carry 90,755 vehicle crossings a day
That is 9.6% of the county's reported daily bridge traffic on 7.9% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 10,084 crossings a day against 6,519 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 114 of 115 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
40% of Schenectady County's bridges have passed the 50-year mark
46 of the 115 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 32.2% 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 25.8% of the county's Poor-condition bridge traffic
RTE I890 over EDISON WYE ERIE/890 Was, built 1966, carries 23,418 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 9-bridge count understates how much of the daily burden sits on a single crossing.
