Loading
Design:
Operating: 35.6 metric ton = 39.2 tons (Load Factor (LF) rating reported by rating factor (RF) method using MS18 loading [6])
Inventory: 22.7 metric ton = 25.0 tons (Load Factor (LF) rating reported by rating factor (RF) method using MS18 loading [6])
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: Better than present minimum criteria [7] and Bridge foundations determined to be stable for assessed or calculated scour conditions; field review indicates action is required. [4]
Inspections
Date: October 2020 [1020] and Frequency: 12
Future Work
Work Needed: Replacement of bridge or other structure because of substandard load carrying capacity or substantial bridge roadway geometry. [31]
