While U.S. road infrastructure continues to be in dire straits, the health of the USA’s bridges has shown a slight improvement from last year when ARTBA found more than 63,000 of the country’s bridges were structurally deficient, according to their review of U.S. Department of Transportation records.

The report on the state of American bridges comes with federal highway and transit funding set to expire on May 31, absent congressional action.

“State and local governments are doing the best they can to address these significant challenges, given limited resources,” said Alison Black, ARTBA’s chief economist. She added, “Without additional investment from all levels of government, our infrastructure spending will be a zero-sum game.”
