Following Transportation for America’s release of a report stating that one in nine bridges is classified as structurally deficient, CNN Money has created an interactive map to demonstrate the amount of deficient bridges in each state in 2013.
According to CNN Money’s report, the average lifespan of a bridge in the U.S. is 50 years. More than 66,000 bridges in the nation are classified as deficient; among those, the average age is 65 years old. The average age of American bridges is 43 years old, so within the next decade, another 25 percent of the nation’s bridges will reach age 65, when they will become more likely to be classified as deficient.
Map data show that Pennsylvania has the largest amount–24.5 percent–of structurally deficient bridges, while Nevada and Florida each have the least amount–2.2 percent–of structurally deficient bridges.
Oklahoma, New York and Louisiana have each seen an increase of more than 50 deficient bridges since 2011, giving these three states the greatest amount of bridge deterioration in the U.S.
And in 2012, 25 percent of U.S. bridges were classified as deficient. (Pennsylvania had the highest number of structurally deficient bridges that year too.)
Despite these figures, the total number of deficient bridges has been reduced in recent years. Pennsylvania, for example, has been working to improve its bridges; the state repaired 8 percent of its deficient bridges since 2011.
And funding improvements may be under way. Just last week, House Democrats introduced a $5.5 billion bill to be spent on bridge repairs, while funding discussions continue to take place among lawmakers.
