Appraisal
Structural: Somewhat better than minimum adequacy to tolerate being left in place as is [5]
Deck Geometry: Basically intolerable requiring high priority of replacement [2]
Road Alignment: Equal to present desirable criteria [8]
Waterway: Equal to present desirable criteria [8] and Bridge is scour critical; bridge foundations determined to be unstable. [3]
Inspections

Future Work
Work Needed: Replacement of bridge or other structure because of substandard load carrying capacity or substantial bridge roadway geometry. [31]
