After reading the measument rules, it is… complicated. From what I can gather, it seem that if any of the components (deck, culverts, sub/superstructure, waterways, etc) receive a ‘poor’ rating, the whole structure is marked as structurally deficient. It also factors in things like the current and expected traffic patterns and mainability.

Water management is one of the biggest headaches in civil engineering - poor performance of any subsystem with a water management role is a legitimate cause for concern.
