The worst bridge in every state
Each state's busiest bridge carrying a poor rating - the definition is stated, the data is federal
United States Bridge Conditions2025 National Bridge Inventory, FHWACompiled
- "Worst" here has a stated, checkable definition: the bridge in each state that carries the most daily traffic on a poor rating in the 2025 National Bridge Inventory (as of ).
- The busiest of them all: Mon Co Rt 19/25 over Scotts Run in Monongalia County, West Virginia, at about 600,500 vehicles a day.
- A poor rating means a major component needs repair; it is not a prediction of failure, and bridges judged unsafe are closed or load-restricted by their owners.
