Federal law mandates the uniform inspection of all bridges for structural and functional adequacy at least every two years; bridges rated ‘deficient’ are eligible for federal repair dollars.
The condition of the nation's highway bridges continued to improve from 2004 to 2005. Of the 596,980 highway bridges in the current National Bridge Inventory, 147,913—about 24.52 percent—were reported deficient for 2005 (see table), a slight improvement from 2004. In 1998 about 29.0 percent were rated deficient. However, progress is slow; at the current rate of improvement, it would take 50 years for the percentage of deficient bridges to be eliminated.
The states vary widely in the percentage of deficient bridges. Nevada reported the lowest percentage of deficient bridges, 3.89 percent, while Rhode Island reported the highest, 53.01 percent.
