State profile · Below median Poor share

Washington 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 Washington.

8,474
Public bridges
50.1%
Good condition
5.5%
Poor condition

Washington has 8,474 public highway bridges in the FHWA's 2024 National Bridge Inventory, and 462 of them are rated Poor.

That is 5.5% 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 24 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.

Washington 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: Washington has 8,474 bridges and a 5.5% Poor-condition share in the 2024 NBI, rank #24 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.
