American Society of Civil Engineers’ 2017 Infrastructure Report Card

The ASCE’s 2017 Infrastructure Report Card continues to give bridges a grade of C+ (“mediocre, requires attention”). “The U.S. has 614,387 bridges, almost four in 10 of which are 50 years or older. 56,007 — 9.1% — of the nation’s bridges were structurally deficient in 2016, and on average there were 188 million trips across a structurally deficient bridge each day.
