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

Future Work
Work Needed: Replacement of bridge or other structure because of substandard load carrying capacity or substantial bridge roadway geometry. [31]
