Structural appraisal:Equal to present minimum criteria [6]
Deck geometry appraisal:Meets minimum tolerable limits to be left in place as is [4]
Underclearances appraisal:Basically intolerable requiring high priority of replacement [2]
Water adequacy appraisal:Somewhat better than minimum adequacy to tolerate being left in place as is [5]
Roadway alignment appraisal:Better than present minimum criteria [7]
Channel protection:Bank protection is being eroded. River control devices and/or embankment have major damage. Trees and rush restrict the channel. [5]
