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: Better than present minimum criteria [7]
Waterway: Equal to present desirable criteria [8] and Bridge foundations determined to be stable for the assessed or calculated scour condition. [8]
