Rapides County Bridge Snapshot

Rapides County, Louisiana contains 523 public highway bridges. Roughly 53.3% are rated “Good,” 39.6% “Fair,” and 7.1% “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.

Rapides County's Poor-condition bridges carry 87,260 vehicle crossings a day

That is 2.1% of the county's reported daily bridge traffic on 7.1% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 2,358 crossings a day against 9,427 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 523 of 523 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

22% of Rapides County's bridges have passed the 50-year mark

115 of the 523 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 53.3% 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 27.6% of the county's Poor-condition bridge traffic

I0049 over BAYOU CLEAR DIV. CANAL, built 1990, carries 24,080 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 37-bridge count understates how much of the daily burden sits on a single crossing.
