Public highway bridges in Delaware
State profile · Below median Poor share
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 Delaware.
Delaware holds 872 public highway bridges (#50 of 52 by inventory) with a 1.26% Poor share (#49 of 52 by Poor share).
That is 1.3% 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 4 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.

What to do with this
Use Delaware'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. Delaware 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.
