The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Hernando County posts a top-10% lowest Poor-condition share among rated counties in the state across rated county bridge 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, Hernando County ranks #7 of 67 Florida counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 0%). Hernando County, Florida contains 60 public highway bridges. Roughly 83.3% are rated “Good,” 16.7% “Fair,” and 0% “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 60 NBI-tracked bridges by lowest applicable component rating.
18 of the 60 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 83.3% 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.
