More than 66,000 bridges in U.S. are deficient

June 25, 2013

More than 66,000 U.S. bridges are classified as deficient, according to a report from our sister site, Better Roads.

The statistic comes from a CNN Money report, which points out that the average lifespan of a U.S. bridge is 50 years, and the average age of U.S. bridges is 43 years old. The report figures that within the next 10 years, another 25 percent will reach age 65, when they are significantly more likely to be classified as deficient.

Of Pennsylvania’s bridges, 24.5 percent are structurally deficient (SD)–the largest amount in the nation. Nevada and Florida have the least amount of SD bridges in the nation; each state has a mere 2.2 percent of SD bridges.

Oklahoma, New York and Pennsylvania have experienced the greatest amount of deterioration in the U.S., with an addition of more than 50 deficient bridges since 2011.

However, the number of deficient bridges has decreased in recent years in some states. Despite its record number of SD bridges, Pennsylvania has repaired 8 percent of its deficient bridges since 2011.

Lawmakers have begun discussing ways to fund bridge repairs, which would further decrease bridge deficiency in the U.S.
