The collapse of the Francis Scott Key Bridge in Baltimore last month underscored the fragility of vulnerable bridge infrastructure all across America.
In fact, hundreds of millions of people are crossing over structurally deficient bridges in the U.S. daily, including in Massachusetts. There are 450 bridges in the state classified as such, according to the Federal Highway Administration’s 2023 National Bridge Inventory. Other local reports have put the number above 600.
It’s estimated that these bridges in Massachusetts see more than 10 million crossings per day.
