Just a sample of a chart of the 245 bridges in the District of Columbia - which has the worst rating in the US.
Keys to using the data below:
Status of “D” means the bridge has been rated structurally deficient; “O” means it has been rated functionally obsolete.
Sufficiency rating is a value obtained by calculating four separate factors (structural adequacy and safety, serviceability and functional obsolescence, essentiality for public use, and special reductions) that is indicative of a bridge’s sufficiency to remain in service. A value of 100 represents an entirely sufficient bridge and a zero represents a deficient bridge.
The raw dataset of the National Bridge Inventory, which is compiled by the U.S. Department of Transportation’s Federal Highway Administration from state reports, used for analysis was provided to MSNBC.com by the National Institute for Computer-Assisted Reporting at the University of Missouri. The most recent data includes inspections through December 2006.
