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 desirable criteria [8]
Waterway: N/A [N] and Bridge not over waterway. [N]
Inspections
