State profile · Near median Poor share

Hawaii 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 Hawaii.

1,195
Public bridges
37.2%
Good condition
6.5%
Poor condition

Hawaii holds 1,195 public highway bridges (#49 of 52 by inventory) with a 6.53% Poor share (#22 of 52 by Poor share).

That is 6.5% 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 31 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.

Hawaii 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: Hawaii has 1,195 bridges and a 6.5% Poor-condition share in the 2024 NBI, rank #31 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.

Who maintains Hawaii’s inventory

State agency holds 62.0% of the 1,195 public highway bridges filed under Hawaii in the 2024 NBI, the agency-of-record split for this state, not a condition verdict.

When Hawaii’s bridges were built

Pre-1950 construction accounts for 32.2% of the 1,195 bridges with a recorded original year in Hawaii. Era bands are orthogonal to the Poor-share ranking above.
