Some background on this data from www.bts.gov: "U.S. totals include the 50 states, the District of Columbia, and Puerto Rico. Structurally deficient bridges are defined as those needing significant maintenance attention, rehabilitation, or replacement. Functionally obsolete bridges are defined as those that do not have the lane widths, shoulder widths, or vertical clearances adequate to serve traffic demand, or the bridge may not be able to handle occasional roadway flooding. Table includes: Rural–Interstate, principal arterial, minor arterial, major collector, minor collector and local roads; Urban–Interstate, other freeways or expressways, other principal arterial, minor arterial, collector, and local roads."

I think a view that shows how many are deficient in some way as compared to not deficient is interesting - even if it's not a good use of screen real estate.
