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: Equal to present desirable criteria [8] and Bridge foundations determined to be stable for the assessed or calculated scour condition. [8]
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]
