Louisiana ranks 7th highest for its share of structurally deficient bridges

Louisiana finished seventh-worst out of 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 states.

Louisiana has a total of 12,899 bridges, with 1,678 designated as structurally deficient, according to the association– or 13 percent of the total number.

Based on the number of bridges in poor condition, Louisiana ranks ninth highest in the U.S.

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.
