What's the Definition of “structurally deficient”?
"Highway bridges have three primary components: 1) the deck, which is the top surface of the bridge that cars, trucks and people cross; 2) the superstructure, which supports the deck; and 2) the substructure, which uses the ground to support the superstructure. Each of these bridge features is given a rating between 0 and 9 when inspected, with 9 signifying the best condition. Federal guidelines classify bridges as “structurally deficient” if one of the three key components is rated at 4 or less (poor or worse), meaning engineers have identified a major defect in its support structure or its deck. (There are a handful of other criteria that can result in a deficient grade, but for the majority of deficient bridges, one of these three primary components rates a 4 or below.) Federal law requires states to inspect all bridges 20 feet or longer at least every two years, though states typically inspect structurally deficient bridges far more often."
