Poor is an FHWA condition category from the lowest applicable component rating (4 or below), not a live crossing-safety or closure decision. Rankings cover counties with at least five public highway bridges.

Canadian County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Canadian County ranks #20 of 77 Oklahoma counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 3.4%). Canadian County, Oklahoma contains 493 public highway bridges. Roughly 49.5% are rated “Good,” 47.1% “Fair,” and 3.4% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale. It is a condition category, not a live safety or closure decision.

Responsible agencies inspect covered bridges on risk-based intervals under current NBIS rules and submit inventory data to FHWA annually. The list below shows every NBI-tracked bridge in the county. Use the “Sort by” controls to change the ordering, and click any row for its reported inspection date, traffic count, and condition fields.

Canadian County's Poor-condition bridges carry 4,070 vehicle crossings a day

That is 0.2% of the county's reported daily bridge traffic on 3.4% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 239 crossings a day against 6,422 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 493 of 493 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

31% of Canadian County's bridges have passed the 50-year mark

153 of the 493 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 49.5% 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 23.8% of the county's Poor-condition bridge traffic

0922C over CREEK, built 1928, carries 970 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 17-bridge count understates how much of the daily burden sits on a single crossing.

What this shows Construction peaked in the 2000s, when 105 of the county's bridges still in the inventory were built, which is 21.3% of those with a recorded year. That cohort is now 15 to 24 years old in the 2024 inventory. Its average build year is 1986, 9 years newer than the Oklahoma average of 1977.
