Substructure: Satisfactory [6]
Loading
Design:
Operating: 32.9 metric ton = 36.2 tons (Allowable Stress(AS) [2])
Inventory: 22.8 metric ton = 25.1 tons (Allowable Stress(AS) [2])
Appraisal
Structural: Somewhat better than minimum adequacy to tolerate being left in place as is [5]
Deck Geometry: Basically intolerable requiring high priority of replacement [2]
Road Alignment: Basically intolerable requiring high priority of corrrective action [3]
Waterway: Equal to present minimum criteria [6] and Bridge foundations determined to be stable for the assessed or calculated scour condition. [8]
Inspections
