Appraisal
Structural:
Deck Geometry: Equal to present desirable criteria [8]
Road Alignment: Basically intolerable requiring high priority of corrrective action [3]
Waterway: Somewhat better than minimum adequacy to tolerate being left in place as is [5] and Bridge is scour critical; field review indicates that extensive scour has occurred at bridge foundations. [2]
Inspections
Date: August 2020 [0820] 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]
