Public bridges: 42.0%
Good condition: 7.7%
Poor condition

Oklahoma holds 22,917 public highway bridges (#9 of 52 by inventory) with a 7.7% Poor share (#17 of 52 by Poor share).

That is 7.7% 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 36 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.
