Nearly 59,000 U.S. bridges still structurally deficient, ARTBA report finds

It’s a mixed bag for the condition of U.S. bridges according to a new analysis of the U.S. DOT’s 2015 “National Bridge Inventory” database.  The good news is there were 2,574 fewer structurally deficient bridges in 2015 compared to the number in 2014. The bad news is there are still 58,500 on the structurally deficient list—and at the current pace of bridge investment—it would take at least 21 years before they were all replaced or upgraded.
