Exhibit 3-31:

Other Arterial Bridge Deficiencies, 1994-2000

Exhibit 3-31

Exhibit 3-31 includes two charts that show the percentage of deficient "other arterial" bridges in rural and urban areas. The vertical axis on the chart on the left, for other deficient rural arterial bridges, measures percentages of other rural arterial bridges from 0 to 40 in increments of 10 percent. The horizontal axis measures the years 1994, 1996, 1998, and 2000. Functionally obsolete other rural arterial bridges dropped from about 12 percent in 1994 and 1996 to 11 percent in 1998 and 2000. Structurally deficient other rural arterial bridges declined steadily from 9 percent in 1994 to about 7 percent in 2000. And the total percentage of deficient other rural arterial bridges declined steadily from about 22 percent in 1994 and 1996 to 14 percent in 1998 and 13 percent in 2000. The vertical axis on the chart on the right, for other deficient urban arterial bridges, also measures percentages of other urban arterial bridges from 0 to 40 in increments of 10 percent, and the horizontal axis also measures the years 1994, 1996, 1998, and 2000. Functionally obsolete other urban arterial bridges stayed at about 23 percent over the time period. Structurally deficient other urban arterial bridges declined steadily from about 12 percent in 1994 to 9 percent in 2000. And the total percentage of deficient other urban arterial bridges declined steadily from about 36 percent in 1994 to 33 percent in 2000.
