Pasco County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Pasco County ranks #23 of 67 Florida counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 1.3%). Pasco County, Florida contains 151 public highway bridges. Roughly 81.5% are rated “Good,” 17.2% “Fair,” and 1.3% “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.

Pasco County's Poor-condition bridges carry 6,960 vehicle crossings a day
That is 0.2% of the county's reported daily bridge traffic on 1.4% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 3,480 crossings a day against 25,815 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.

25.8% of Pasco County's bridges have passed the 50-year mark
39 of the 151 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 81.5% 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 94.8% of the county's Poor-condition bridge traffic
GRAND BLVD. CR-595 over PITHLACHASCOTEE RIVER, built 1957, carries 6,600 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 2-bridge count understates how much of the daily burden sits on a single crossing.
