Structurally deficient

From: 2015 "Status of the Nation’s Highways, Bridges, and Transit: Conditions and Performance" report to Congress

Bridges are considered “structurally deficient” if (1) significant load-carrying elements are found to be in poor or worse-than-poor condition due to deterioration or damage, or (2) the adequacy of the waterway opening the bridge provides is determined to be insufficient to the point of causing intolerable traffic interruptions due to high water. That a bridge is structurally deficient does not mean it is unsafe.
