Comanche County, Oklahoma contains 593 public highway bridges. Roughly 32.4% are rated “Good,” 58.9% “Fair,” and 8.8% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale.

Comanche County's Poor-condition bridges carry 35,361 vehicle crossings a day

That is 2.1% of the county's reported daily bridge traffic on 8.8% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 680 crossings a day against 2,869 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 593 of 593 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

48.1% of Comanche County's bridges have passed the 50-year mark

285 of the 593 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 32.4% 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 42.4% of the county's Poor-condition bridge traffic

FAU 7681 (SHERIDAN over NUMU CREEK, built 1942, carries 14,994 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 52-bridge count understates how much of the daily burden sits on a single crossing.
