The vertical axis has bars for 13 types of functional systems, and the horizontal bar measures percentages from 0 to 40 in increments of 5 percent. 17 percent of rural interstate bridges were functionally obsolete, and 4 percent were structurally deficient. 27 percent of urban interstate bridges were functionally obsolete, and 7 percent were structurally deficient. 27 percent of other urban freeway and expressway bridges were functionally obsolete, and 6 percent were structurally deficient. 16 percent of other rural principal arterial bridges were functionally obsolete, and just over 5 percent were structurally deficient. 33 percent of other urban principal arterial bridges were functionally obsolete, and 10 percent were structurally deficient. 21 percent of rural minor arterial bridges were functionally obsolete, and 8 percent were structurally deficient. 37 percent of urban minor arterial bridges were functionally obsolete, and 12 percent were structurally deficient. 23 percent of rural major collector bridges were functionally obsolete, and 12 percent were structurally deficient. 27 percent of rural minor collector bridges were functionally obsolete, and 15 percent were structurally deficient. 37 percent of urban collector bridges were functionally obsolete, and 13 percent were structurally deficient. Just under 35 percent of rural local bridges were functionally obsolete, and 23 percent were structurally deficient. 32 percent of urban local bridges were functionally obsolete, and 13 percent were structurally deficient. And an average of 28 percent of all rural and urban bridges were functionally obsolete, and 15 percent were structurally deficient.
