A total of 150 out of the 8,294 bridges in Arizona – or 1.8 percent – were designated in poor shape in an analysis examining bridge conditions in the 50 states, Puerto Rico and Washington, D.C.

More than 47,000 bridges in the United States, out of a total of 616,087, were rated structurally deficient in a study released by the American Road & Transportation Builders Association (ARTBA). If the deficient bridges were placed end to end, they would extend more than 1,000 miles, the report says.

Arizona had the third lowest highest percentage of structurally deficient bridges nationwide, the ARTBA study found.  

Based on the number of its bridges in poor condition, Arizona ranks 46th highest in the nation.

The bridges identified are not considered imminently unsafe, according to the analysis, but they do need attention. The number of people crossing these bridges each day is estimated at 178 million.

States that have reduced their number of deficient bridges the most in the last five years include Pennsylvania, Oklahoma, Indiana, California and Ohio, the association reported, while the states where the number of problematic bridges increased include West Virginia, Illinois, Florida, Montana and Louisiana.

The data for the study came from the U.S. Department of Transportation’s National Bridge Inventory and is based on 2018 numbers.
