Appraisal
Structural: Meets minimum tolerable limits to be left in place as is [4]
Deck Geometry: Basically intolerable requiring high priority of replacement [2]
Road Alignment: Equal to present desirable criteria [8]
Waterway: Somewhat better than minimum adequacy to tolerate being left in place as is [5] and Bridge foundations determined to be stable for assessed or calculated scour condition. [5]
