According to American Road & Transportation Builders Association (ARTBA), there are 612,677 bridges in the United States, but 54,259 of them are rated “structurally deficient” and pose a risk to the millions of drivers passing over them on a daily basis. The average age of a structurally deficient bridge in the U.S. is 67 years, compared to 40 years for non-deficient bridges. ARTBA warned that at the current pace of bridge repair and replacement work, it will take 37 years to remedy all the nation’s current structurally deficient bridges.

On Tuesday’s state of the Union address to the American people, President Trump announced his proposal for a $1.5 trillion infrastructure program, though he failed to explain exactly how the program would work as the federal government would provide very little money for America’s crumbling bridges, rails, roads, and waterways. State transportation officials warned that significant hikes to taxes, fees, and tolls might be required by local governments to fund such repairing projects.
