Arizona finished 50th among the 50 states, Puerto Rico and Washington, D.C., in a new analysis examining which states have the highest percentage of bridges in poor condition.
More than 47,000 bridges in the United States, out of a total of 616,087, were rated structurally deficient in a study released last month by the American Road & Transportation Builders Association. If the deficient bridges were placed end to end, they would extend more than 1,000 miles, the report says.
Arizona has a total of 8,294 bridges, with 150 designated as structurally deficient, according to the association. That works out to 1.8 percent of the total number.
Based on the number of 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.
