Fairfield County, Ohio contains 320 public highway bridges. Roughly 56.6% are rated “Good,” 38.4% “Fair,” and 5% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale.

Fairfield County's Poor-condition bridges carry 36,313 vehicle crossings a day

That is 2.9% of the county's reported daily bridge traffic on 5% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 2,270 crossings a day against 4,603 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.

40.6% of Fairfield County's bridges have passed the 50-year mark

130 of the 320 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 56.6% 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 27.4% of the county's Poor-condition bridge traffic

GRE-22 CAMP GROUND over T HOCKING RV(CAMP GROUND, built 1985, carries 9,964 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 16-bridge count understates how much of the daily burden sits on a single crossing.
