According to a new report by the American Road and Transportation Builders Association, if bridge repairs occur at the current pace, it will take 80 years to repair all structurally deficient bridges, The Hill reports.
The group fighting for more investment in transportation infrastructure found that 47,052 of the 616,087 bridges in the United States, or almost eight percent, are "structurally deficient" and urgently require repair. Almost 50 percent of all bridges across the country are in need of some form of repair.
Many of the structurally unsound bridges are major landmarks like the Brooklyn Bridge and the Memorial Bridge from the Lincoln Memorial to Arlington, VA. The report found that Americans cross these bridges 178 million times every day.
Iowa had the highest number of these unsafe bridges with 4,675, followed by Pennsylvania with 3,770. Road Island and West Virginia had the highest percentage of structurally deficient bridges relative to the total number of bridges in each state, with 23 percent and 19.8 percent, respectively.
“While these bridges may not be imminently unsafe, they are in need of attention,” the report reads. “Nearly 69,000 bridges across the country are ‘posted for load’, which means there are weight restrictions or other measures in place to reduce stress on the structure.”
