POINT OF ROCKS
Condition
Deck: Satisfactory [6]
Superstructure: Fair [5]
Substructure: Fair [5]
Loading
Design: M 18 / H 20 [4]
Operating: 35.4 metric ton = 38.9 tons (Load Factor(LF) [1])
Inventory: 20.9 metric ton = 23.0 tons (Load Factor(LF) [1])
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 minimum criteria [6]
Waterway: Equal to present desirable criteria [8] 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]
