The U.S. Department of Transportation reports that nearly 25 percent of bridges in the U.S. - over 152,000 bridges - are "structurally deficient or functionally obsolete." Heavier vehicles, like school buses and delivery trucks, are forced to take lengthy detours for safer bridges. Nearly one in four miles of urban interstate is in "poor" or "mediocre" condition.
