Ohio 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 Ohio.

Public bridges
61.0%
Good condition
4.7%
Poor condition

Ohio holds 26,729 public highway bridges (#3 of 52 by inventory) with a 4.74% Poor share (#35 of 52 by Poor share).

That is 4.7% 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 18 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.

Ohio 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: Ohio has 26,729 bridges and a 4.7% Poor-condition share in the 2024 NBI, rank #18 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.
