Latest Available Inspection: August 2018

Good/Fair/Poor Condition:Poor
Status:Posted for load [P]
Average daily traffic:300 [as of 2005]
Truck traffic:2% of total traffic
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:Somewhat better than minimum adequacy to tolerate being left in place as is [5]
Roadway alignment appraisal:Basically intolerable requiring high priority of corrrective action [3]
Channel protection:Bank protection has failed. River control devices have been destroyed. Stream bed aggradation, degradation or lateral movement has changed the channel to now threaten the bridge and/or approach roadway. [3]
Pier/abutment protection:None present but re-evaluation suggested [5]
Culvert condition:Integral wingwalls collapsed, severe settlement of roadway due to loss of fill. Section of culvert may have failed and can no longer support embankment. Complete undrmining at curtain walls and pipes. Corrective action required to maintain traffic. Metal culverts have extreme distortion and deflection and deflection throughout with extensive perforations due to corrosion. [2]
Scour condition:Bridge is scour critical; bridge foundations determined to be unstable. [3]
Sufficiency rating:20.0
Recommended work:Replacement of bridge or other structure because of substandard load carrying capacity or substantial bridge roadway geometry. [31]
Estimated cost of work:$198,000
