According to the Federal Highway Administration's 2024 National Bridge Inventory, condition ratings, load ratings, and Poor-condition shares for every public highway bridge in Florida.

Compiled by PlainBridges

13,036
Public bridges: 59.5%
Good condition: 2.8%
Poor condition

Florida holds 13,036 public highway bridges (#22 of 52 by inventory) with a 2.79% Poor share (#46 of 52 by Poor share).

That is 2.8% of the state's inventory, against an average of 7.5% across the 54 states and territories with Poor-rated bridges on file, which places it 7 of 54 ordered from the lowest Poor share upward. A bridge is rated Poor when its weakest applicable component scores 4 or below on the inspecting agency's 0-9 scale, so the category is a maintenance and funding signal rather than a closure order or a live crossing-safety verdict.
