BridgeCondition — US Bridge Condition Reports & Safety Ratings
Federal inspection data for 624,191 bridges, rewritten as reports that a neighbour, a local journalist or an engineer can actually read.
Public infrastructure data, finally readable
The United States inspects its bridges and publishes the results — but the National Bridge Inventory is a federal dataset written for engineers, not for the public. "What condition is the bridge I cross every morning in?" was a question with no easy answer.
BridgeCondition is an own product built to answer it. It ingests FHWA inspection records and publishes readable reports for 624,191 bridges, complete with search, rankings and statistics. The audience ranges from curious residents to local reporters and infrastructure watchers.

Architecture and performance
Serving hundreds of thousands of detail pages with geographic filtering is beyond any stock CMS. BridgeCondition is custom-built: a Laravel + PHP backend over a MySQL database indexed to answer state, county, city and condition queries without sacrificing page speed.
SEO-wise it is programmatic end to end — the state → county → bridge hierarchy produces clean, heavily interlinked URLs that crawlers can traverse in full. No templates, no plugins.
Bridge data FAQ
Where does the bridge data come from?
From the FHWA National Bridge Inventory, the federal dataset that compiles inspection records for bridges across the United States. BridgeCondition restructures those records into a readable report per bridge.
How many bridges are covered?
The homepage counts 624,191 bridges across 53 states and territories, with an average age of 48 years. 41,684 of them are currently rated in Poor condition on the federal scale.
What do Good, Fair and Poor actually mean?
They map to the FHWA rating scale: Good covers ratings 7-9 (key structural components in good health), Fair covers 5-6 (visible deterioration but structurally adequate for travel) and Poor covers 0-4 (may need significant repair or replacement).
How do I look up a specific bridge?
Search by bridge name, city, county or route to open its condition ratings, inspection dates and structural details — or browse by state, filter by condition category, and check the Worst Bridges rankings for any area.
