How to Check the Bridges You Cross Daily
A practical guide for commuters, how to look up bridge condition data on PlainBridges for bridges on your daily route and what to do with what you find.
On this register · 2024 NBI
According to the Federal Highway Administration's 2024 National Bridge Inventory.
The lookup reads the same 623,216-record federal file as every county page. A Poor row is a lowest component rating of 4 or below: Iowa 19.16% versus Nevada 1.14% among 49 large inventories, not a live outage board.

Use the structure number or place name; the record is the last submitted inspection, not whether the span is open today.
Three ways to find your bridge
Use the search tool with a nearby road, feature crossed (river, highway, rail line), or place name; results link straight to the bridge's own page. If you know your state and county, the state directory lets you browse by county instead. If you already have an NBI structure number (often posted on a small plate on the bridge itself), search that directly for an exact match.
What you'll see on a bridge page
Each bridge page shows its overall Good/Fair/Poor condition, the year built, material, owner agency, and average daily traffic, all sourced from the same NBI record. The condition reflects the bridge's most recent inspection, not a live status board, see how the 0-9 rating works for what the category actually means.
Context before you worry
A Poor rating on a bridge you cross daily is worth noticing, but it isn't by itself a reason to avoid the crossing, the responsible owner posts weight restrictions or closes a bridge when current use is unsafe, not the inspection record alone. Construction era is useful context too: an older bridge isn't automatically worse, and a newer one isn't automatically better, maintenance history matters more than the year on the nameplate.
Construction era, nationwide
Every bridge in the 2024 NBI file, grouped by the era it was built, useful context before you look up your own.
What to do if you see something
A data record is never a substitute for what you can see yourself. Visible damage, cracking, or debris under a bridge you cross should be reported directly, see how to report a damaged or unsafe bridge and who to contact based on the bridge's owner.
What to do with this
The record shows the last inspection, not today's status, use it to get informed, not to replace what you can see yourself.
- Search by road name, crossing, or structure number to find the exact bridge you cross, not just its county. Search bridges
- A Poor rating means the owner decides load restriction or closure, it is not itself a closure notice. What a Poor rating means
- See visible damage on a bridge you cross? Report it directly rather than waiting for the next scheduled inspection. How to report a bridge
Construction-era figures are the current FHWA 2024 NBI file; individual bridge pages reflect the most recent submitted inspection, not a live status feed.
