Inventory: 4 metric ton = 4.4 tons (Allowable Stress(AS) [2])
Appraisal
Structural: Basically intolerable requiring high priority of replacement [2]
Deck Geometry: Somewhat better than minimum adequacy to tolerate being left in place as is [5]
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]
Inspections
Date: October 1999 [1099] and Frequency: 24
Future Work
Work Needed: Replacement of bridge or other structure because of substandard load carrying capacity or substantial bridge roadway geometry. [31]
