Steuben County's Poor-condition bridges carry 17,382 vehicle crossings a day

That is 0.8% of the county's reported daily bridge traffic on 4.2% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 669 crossings a day against 2,181 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 625 of 627 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

37.2% of Steuben County's bridges have passed the 50-year mark

233 of the 627 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 41.5% 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 17.2% of the county's Poor-condition bridge traffic

COUNTY ROAD 115 over S B GLENDENING CK, built 1937, carries 2,998 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 26-bridge count understates how much of the daily burden sits on a single crossing.
