Last week, the port of Baltimore finally reopened fully for the first time since the tragic collapse of the Francis Scott Keys Bridge last March. Maryland Governor Wes Moore stated in a press release, “One of our four key directives in the wake of the Key Bridge collapse has been to fully clear the federal channel. Today, we bring that directive to completion. By working together, we turned months into weeks – and bounced back faster than many could have ever anticipated.” Engineers at Johns Hopkins University are currently investigating what led to the devastating bridge failure and what other bridges across the country are at risk.

At 24/7 Wall St., we took a deep dive into the data to uncover which bridges across the country are the most vulnerable. Using the Libertarian Reason Foundation’s 27th Annual Highway Report, we listed states in order of the percentage of structurally deficient bridges, ranking from lowest to highest. The report provides overall highway performance scores ranging from 1 to 50, with 50 being the best. The rankings are generated using 13 category scores, including deficient bridges, traffic fatalities, traffic congestion, urban and rural pavement conditions, spending per mile, and administrative costs per mile of highway. And finally, we’ve included each state’s most impressive bridge, which came from Love Exploring.

The Reason Foundation report found that of all the states, Florida made the most improvements nationwide in one year, jumping 33 spots from 41st to 8th in the overall rankings from 2020 to 2021. On the other hand, Idaho fell the farthest, from 8th to 34th. (Also see: This State Has the Worst Highways in America.)

The report revealed overall, the state of the nation’s bridges improved only slightly from 2020 to 2021, from 45,861 structurally deficient bridges in 2020 to 43,289 in 2021. The worst offender on the list is West Virginia, with over 20% of its bridges deemed structurally deficient, while Arizona sits on top with only 1.38% of structurally deficient bridges.

What is the condition of bridges in your state? Read on to find out how each state ranks.

Why This Matters

Many Americans cross bridges each day on their daily commute. Reliable bridges are critical for public safety and the nation’s economy. However, most bridges in America were built to last 50 to 70 years, and 42% of bridges are at least 50 years old. While bridges get inspected every two years, and those deemed deficient are eligible for federal funding for repairs, it’s the policymakers that allocate funds for infrastructure improvements. Unless we increase spending on bridge rehabilitation, it will take many years to get America’s bridges back in shape.
