Appraisal
Structural: Meets minimum tolerable limits to be left in place as is [4]
Deck Geometry: Better than present minimum criteria [7]
Road Alignment: Basically intolerable requiring high priority of corrrective action [3]
Waterway: Equal to present desirable criteria [8] and Bridge is scour critical; bridge foundations determined to be unstable. [3]
