Ya, this bridge is a result of the Town of Florence, Florence County Wisconsin and the Dickinson County Road Commission, Dickinson County Michigan not willing to come together and discuss what to do, each own half. They have taken the "do nothing" approach until it becomes a navagational hazard and the DNR orders it removed.
I have reciently nominated it to the Nation Register of Historical Places to hopefully gain public awareness and support. In my research I came across pictures of the concrete deck being poured and it is still the original concrete deck, so this "divide" goes back over a hundred years.
Seriously... they are willing to scrap the last on of its kind in Michigan or Wisconsin rather than form a joint committee and discuss the options......
