North Carolina 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 North Carolina.

19,210
Public bridges
43.8%
Good condition
6.8%
Poor condition

North Carolina holds 19,210 public highway bridges (#12 of 52 by inventory) with a 6.76% Poor share (#21 of 52 by Poor share).

That is 6.8% 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 32 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.

North Carolina 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: North Carolina has 19,210 bridges and a 6.8% Poor-condition share in the 2024 NBI, rank #32 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.
