Kentucky bridge safety

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 Kentucky.

14,548
Public bridges
26.6%
Good condition
7.4%
Poor condition

Kentucky holds 14,548 public highway bridges (#18 of 52 by inventory) with a 7.37% Poor share (#19 of 52 by Poor share).

That is 7.4% 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 34 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.

Kentucky in the national condition pattern

Each point is a state or territory in the FHWA NBI; the highlighted point is this profile.

Inventory size and Poor-condition share are different measures: Kentucky has 14,548 bridges and a 7.4% Poor-condition share in the 2024 NBI, rank #34 of 54 jurisdictions ordered from the lowest share upward. The dashed comparisons mark the national average state rate and the midpoint of the plotted inventory range; neither is a live safety or closure threshold.
