Latest Available Inspection: July 2018

Good/Fair/Poor Condition:Poor
Status:Open, no restriction [A]
Average daily traffic:3,600 [as of 2015]
Truck traffic:14% of total traffic
Deck condition:Fair [5 out of 9]
Superstructure condition:Fair [5 out of 9]
Substructure condition:Poor [4 out of 9]
Structural appraisal:Meets minimum tolerable limits to be left in place as is [4]
Deck geometry appraisal:Basically intolerable requiring high priority of corrrective action [3]
Water adequacy appraisal:Better than present minimum criteria [7]
Roadway alignment appraisal:Equal to present desirable criteria [8]
Channel protection:Bank protection is being eroded. River control devices and/or embankment have major damage. Trees and rush restrict the channel. [5]
Pier/abutment protection:In place and functioning [2]
Scour condition:Bridge foundations determined to be stable for the assessed or calculated scour condition. [8]
Sufficiency rating:32.0
