The American Road and Transportation Builders Association reported earlier this year that in 2015, nearly 10% of the nation’s 600,000 bridges were structurally deficient, and the USDOT said there was a 21-year, $115 billion backlog for bridge repairs as long as the country invested in them at its current pace.
While the ARTBA survey covered all stages of repairs, the association said its primary concern was the soundness of older bridges that had seen heavy use.
