Duval County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Duval County ranks #28 of 67 Florida counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 1.8%). Duval County, Florida contains 831 public highway bridges. Roughly 63.7% are rated “Good,” 34.5% “Fair,” and 1.8% “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.

Duval County's Poor-condition bridges carry 537,294 vehicle crossings a day

That is 2.1% of the county's reported daily bridge traffic on 1.8% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 35,820 crossings a day against 30,286 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 831 of 831 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

41.8% of Duval County's bridges have passed the 50-year mark

347 of the 831 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 63.7% 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 23.5% of the county's Poor-condition bridge traffic

I-95 (SR-9) over 13th ST., built 1959, carries 126,500 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 15-bridge count understates how much of the daily burden sits on a single crossing.

Share is of the 537,294 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.
