Appraisal
Structural: Basically intolerable requiring high priority of replacement [2]
Deck Geometry: Basically intolerable requiring high priority of corrrective action [3]
Road Alignment: Somewhat better than minimum adequacy to tolerate being left in place as is [5]
Waterway: Somewhat better than minimum adequacy to tolerate being left in place as is [5] and Bridge foundations determined to be stable for the assessed or calculated scour condition. [8]
Inspections
Date: November 1999 [1199] and Frequency: 24
