Orange County, Florida contains 885 public highway bridges. Roughly 75.6% are rated “Good,” 24.3% “Fair,” and 0.1% “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.

Orange County's Poor-condition bridges carry 19,250 vehicle crossings a day
That is 0.1% of the county's reported daily bridge traffic on 0.1% of its bridges: Poor-condition structures carry the same share of traffic than their share of the inventory. Each Poor bridge averages 19,250 crossings a day against 31,971 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.

16.7% of Orange County's bridges have passed the 50-year mark
148 of the 885 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 75.6% 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 100% of the county's Poor-condition bridge traffic
Conroy Road over I-4, built 2000, carries 19,250 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 1-bridge count understates how much of the daily burden sits on a single crossing.
