Lincoln County, Louisiana contains 171 public highway bridges. Roughly 22.8% are rated “Good,” 63.7% “Fair,” and 13.5% “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.

Lincoln County's Poor-condition bridges carry 137,775 vehicle crossings a day
That is 12.6% of the county's reported daily bridge traffic on 13.6% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 5,990 crossings a day against 1,213 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.

38% of Lincoln County's bridges have passed the 50-year mark
65 of the 171 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 22.8% 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 36.9% of the county's Poor-condition bridge traffic
I0020 over CREEK, built 1963, carries 50,895 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 23-bridge count understates how much of the daily burden sits on a single crossing.
