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.

Oklahoma County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Oklahoma County ranks #34 of 77 Oklahoma counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 6%). Oklahoma County, Oklahoma contains 1,216 public highway bridges. Roughly 38.2% are rated “Good,” 55.8% “Fair,” and 6% “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.

Oklahoma County's Poor-condition bridges carry 566,311 vehicle crossings a day

That is 3.1% of the county's reported daily bridge traffic on 6% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 7,758 crossings a day against 15,826 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 1,216 of 1,216 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

38.7% of Oklahoma County's bridges have passed the 50-year mark

471 of the 1,216 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 38.2% 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 17.5% of the county's Poor-condition bridge traffic

I-240 over I-35 UNDER, built 1959, carries 99,100 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 73-bridge count understates how much of the daily burden sits on a single crossing.

Share is of the 566,311 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.

What this shows Construction peaked in the 1970s, when 195 of the county's bridges still in the inventory were built, which is 16% of those with a recorded year. That cohort is now 45 to 54 years old in the 2024 inventory. Its average build year is 1982, 5 years newer than the Oklahoma average of 1977.
