Truck traffic:26% of total traffic
Deck condition:Poor [4 out of 9]
Superstructure condition:Poor [4 out of 9]
Substructure condition:Fair [5 out of 9]
Structural appraisal:Basically intolerable requiring high priority of replacement [2]
Deck geometry appraisal:Basically intolerable requiring high priority of corrrective action [3]
Water adequacy appraisal:Equal to present minimum criteria [6]
Roadway alignment appraisal:Somewhat better than minimum adequacy to tolerate being left in place as is [5]
