State profile · Below median Poor share

Oregon 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 Oregon.

8,305
Public bridges
33.3%
Good condition
4.6%
Poor condition

Oregon holds 8,305 public highway bridges (#30 of 52 by inventory) with a 4.61% Poor share (#37 of 52 by Poor share).

That is 4.6% 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 16 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.

Oregon 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: Oregon has 8,305 bridges and a 4.6% Poor-condition share in the 2024 NBI, rank #16 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 Oregon’s inventory

State agency holds 34.3% of the 8,305 public highway bridges filed under Oregon in the 2024 NBI, the agency-of-record split for this state, not a condition verdict.

When Oregon’s bridges were built

Pre-1950 construction accounts for 8.8% of the 8,305 bridges with a recorded original year in Oregon. Era bands are orthogonal to the Poor-share ranking above.
