McCurtain County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, McCurtain County ranks #62 of 77 Oklahoma counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 11.7%). McCurtain County, Oklahoma contains 265 public highway bridges. Roughly 54.3% are rated “Good,” 34% “Fair,” and 11.7% “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.

McCurtain County's Poor-condition bridges carry 7,985 vehicle crossings a day

That is 2.4% of the county's reported daily bridge traffic on 11.7% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 258 crossings a day against 1,733 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 265 of 265 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

58.9% of McCurtain County's bridges have passed the 50-year mark

156 of the 265 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 54.3% 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 38.8% of the county's Poor-condition bridge traffic

S.H. 3 over GLOVER RIVER, built 1953, carries 3,100 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 31-bridge count understates how much of the daily burden sits on a single crossing.
