Sufficiency rating of 3%? Based on experience with other historic bridge types such as metal truss and concrete arch, this bridge's condition requires removal and replacement with a two lane pre-stressed adjacent box beam structure, despite any historic value and/or preservation potential. But its a covered bridge so they will probably rehab for continued vehicular use.
