What does it mean to be structurally deficient?
Structurally deficient means there are elements of the bridge that need to be monitored and/or repaired. The fact that a bridge is “structurally deficient” does not imply that it is likely to collapse or that it is unsafe. It means the bridge must be monitored, inspected and maintained.
What must be included in a bridge database?

When does a deck become functionally obsolete?
Functionally obsolete (FO) is the state in which the deck geometry, load carrying capacity (comparison of the original design load to the State legal load), clearance, or approach roadway alignment no longer meets the usual criteria for the system of which it is an integral part.
