The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Webster County pairs a higher-than-median Poor-condition share among rated counties in the state with an older average build year than the state inventory.
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.
According to the Federal Highway Administration's 2024 National Bridge Inventory, Webster County ranks #59 of 64 Louisiana counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 25.3%). Webster County, Louisiana contains 194 public highway bridges. Roughly 21.6% are rated “Good,” 53.1% “Fair,” and 25.3% “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.

Share of 194 NBI-tracked bridges by lowest applicable component rating.
That is 9.2% of the county's reported daily bridge traffic on 25.3% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 2,003 crossings a day against 3,707 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 194 of 194 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
89 of the 194 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 21.6% 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.
LA0159 over KCS RR MINDEN, built 1960, carries 9,864 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 49-bridge count understates how much of the daily burden sits on a single crossing.
Share is of the 98,168 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.
