Appraisal
Structural: Basically intolerable requiring high priority of corrrective action [3]
Deck Geometry: Somewhat better than minimum adequacy to tolerate being left in place as is [5]
Road Alignment: Equal to present desirable criteria [8]
Waterway: Equal to present desirable criteria [8] and Bridge foundations determined to be stable for assessed or calculated scour conditions; field review indicates action is required. [4]
