Functionally obsolete

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

Functional obsolescence in general is a function of the geometrics (e.g., broad roadway width, load carrying capacity, clearances, approach roadway alignment) of the bridge in relation to the geometrics required by current design standards. The magnitude of such deficiencies determines whether a bridge is classified as “functionally obsolete.”
