The number of bridges in poor condition has declined since 2014 in the United States but at a slower rate than in the past, according to the American Road & Transportation Builders Association’s new bridge report.
“At the current pace, it would take more than 80 years to replace or repair the nation’s structurally deficient bridges,” says Alison Premo Black, ARTBA chief economist. “That’s longer than the average life expectancy of a person living in the U.S.”
Black conducted ARTBA’s annual analysis of the federal 2018 National Bridge Inventory database and determined that 47,052, or 7.6 percent, of the nation’s bridges are deemed structurally deficient.
Last year saw only a 1 percentage point drop in the number of bridges on the list, the slowest rate in five years.
