The old saying that a picture is worth thousand words still holds ground. The website of the House Transportation and Infrastructure Committee has posted a map of the United States showing locations of the structurally deficient bridges on the National Highway System. Some numbers by states are also available on the website, such as 73,784 bridges are structurally deficient out of a total of 597,340 bridges in the U.S. That makes a little more than 12% bridges as structurally deficient. More than 5% bridges on the National Highway System are structurally deficient. In Indiana, 11.3% or 2,066 out of a total of 18,364 bridges are structurally deficient.
The events like the Minnesota Bridge Collapse remind us about our crumbling infrastructure system. A structurally deficient bridge is not necessarily unsafe but this indicates the enormous task ahead of maintaining and upgrading the transportation infrastructure system.
