Appraisal
Structural: Basically intolerable requiring high priority of replacement [2]
Deck Geometry: Equal to present minimum criteria [6]
Road Alignment: Meets minimum tolerable limits to be left in place as is [4]
Waterway: Somewhat better than minimum adequacy to tolerate being left in place as is [5] and Bridge is scour critical; bridge foundations determined to be unstable. [3]
