Appraisal
Structural: Somewhat better than minimum adequacy to tolerate being left in place as is [5]
Deck Geometry: Basically intolerable requiring high priority of corrrective action [3]
Road Alignment: Equal to present minimum criteria [6]
Waterway: Better than present minimum criteria [7] and Bridge foundations determined to be stable for the assessed or calculated scour condition. [8]
