Lincoln County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Lincoln County ranks #68 of 77 Oklahoma counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 13.3%). Lincoln County, Oklahoma contains 450 public highway bridges. Roughly 37.1% are rated “Good,” 49.6% “Fair,” and 13.3% “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.

Lincoln County's Poor-condition bridges carry 15,255 vehicle crossings a day

That is 1.9% of the county's reported daily bridge traffic on 13.3% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 254 crossings a day against 3,172 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 450 of 450 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

44.4% of Lincoln County's bridges have passed the 50-year mark

200 of the 450 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 37.1% 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 51.1% of the county's Poor-condition bridge traffic

S.H. 66 over SLWC R.R. UNDER, built 1926, carries 7,800 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 60-bridge count understates how much of the daily burden sits on a single crossing.
