50 of the Most Dangerous Bridges in America

By Patrick Wilson

As smart as structural and civil engineers are, as ingenious as their designs may be, and as durable as their bridges may appear, nothing is so permanent to withstand the forces of time and nature. Add to it the ubiquitousness of automobiles in the early twentieth century, and bridges—specifically American bridges—undergo an aging process that ranks behind many developed nations around the world.

"In 2016 the World Bank provided an interesting annual Global Ranking related to infrastructure quality," says Justin Loera, Senior Insurance Market Analyst at Auto Insurance Center, a news site that offers analysis on all things relating to automotives. "The United States ranked eighth in the world in national infrastructure quality, behind Germany and the U.K., but above France and Canada." Loera and his team recently unveiled a study spotlighting the most dangerous bridge from each state in America. They pinpointed bridges that were structurally deficient, or in Loera's terms, "when one or more of the key bridge components—such as the deck, superstructure, or substructure—was considered to be in poor condition or worse." Of course, structurally deficient bridges pose a real risk of collapsing— as it happened in Minneapolis in 2007, killing a total of seven people .
