A new report from the American Road and Transportation Builders Association reveals that more than 54,000 bridges on U.S. interstates and highways are rated “structurally deficient.”

Of the 612,677 bridges in the U.S., 54,259 of them (or 8.8 percent) are considered “structurally deficient,” meaning these bridges may not be unsafe at the moment but are in need of attention and repair, ARTBA says.

In analyzing the U.S. Department of Transportation’s 2017 National Bridge Inventory database, ARTBA found that in the nearly 48,000 miles of the Interstate Highway System, an average of one bridge every 27 miles is considered “structurally deficient.”
