Interactive Report: Our Deficient Bridges

Posted by Joe Gentle on Monday, February 27th, 2017

A new interactive report from the American Road & Transportation Builders Association (ARTBA) draws attention to the tens of thousands of bridges deemed structurally deficient throughout the United States. The term “structurally deficient” means that at least one of the key bridge elements–the deck, superstructure or substructure–is in poor condition.

According to the report, there are 56,000 bridges nationwide that meet this criteria, and over 1,900 of them are on the Interstate Highway System. Iowa alone accounts for nearly 5,000 structurally deficient bridges, making up over 20% of the state’s total bridge inventory. Nevada, at the other end of the spectrum, contains only 31 structurally deficient bridges, amounting to just 1.6% of its total.
