Vermilion County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Vermilion County ranks #35 of 64 Louisiana counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 11.1%). Vermilion County, Louisiana contains 261 public highway bridges. Roughly 45.6% are rated “Good,” 43.3% “Fair,” and 11.1% “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.

Vermilion County's Poor-condition bridges carry 60,910 vehicle crossings a day

That is 14.1% of the county's reported daily bridge traffic on 11.1% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 2,100 crossings a day against 1,618 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 261 of 261 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

42.1% of Vermilion County's bridges have passed the 50-year mark

110 of the 261 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 45.6% 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.

One structure carries 32.5% of the county's Poor-condition bridge traffic

LA0014-B over VERMILION R/ABBEVILLE, built 1964, carries 19,800 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 29-bridge count understates how much of the daily burden sits on a single crossing.
