State profile · Below median Poor share

Utah 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 Utah.

3,125
Public bridges
22.2%
Good condition
2.9%
Poor condition

Utah holds 3,125 public highway bridges (#42 of 52 by inventory) with a 2.91% Poor share (#44 of 52 by Poor share).

That is 2.9% 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 9 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.

Utah 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: Utah has 3,125 bridges and a 2.9% Poor-condition share in the 2024 NBI, rank #9 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 Utah’s inventory

State agency holds 61.1% of the 3,125 public highway bridges filed under Utah in the 2024 NBI, the agency-of-record split for this state, not a condition verdict.

When Utah’s bridges were built

Pre-1950 construction accounts for 5.9% of the 3,125 bridges with a recorded original year in Utah. Era bands are orthogonal to the Poor-share ranking above.

What to do with this

Use Utah's inventory picture to drill to a county or a specific span.

NBI condition ratings are inventory snapshots, not live crossing-safety verdicts.

Every figure on PlainBridges is rendered directly from federal source data, no number is typed in by an editor. Utah Good/Fair/Poor shares and county rollups on this page are computed from the same NBI extract as the national boards; no figure is typed in by an editor. See our editorial standards & corrections policy, the methodology behind these numbers, or report a data error. Data current as of 2024 NBI release. NBI condition categories reflect the latest reported inventory record, not a live safety, closure, or travel decision.
