DOT Report: More than 63,000 bridges need repair; Problem severe in key soybean producing states

Recent analysis by the U.S. Department of Transportation reveals the nation has a total of 63,000 bridges that are rated as structurally deficient and in need of repair. Of particular concern to farmers, many of the states with the highest number and/or the highest percentage of structurally deficient bridges are those with sizable soybean production.

A structurally deficient bridge is classified as requiring significant maintenance, rehabilitation, or replacement.
