NOTES: Functionally obsolete refers to bridges
that do not have the lane widths, shoulder widths, or vertical clearances
adequate to serve traffic demand, or the bridge may not be able to handle
occasional roadway flooding. Structurally deficient refers to bridges needing
significant maintenance attention, rehabilitation, or replacement.
