It has to be a vehicular/road bridge, as it has an inspection date and vehicle per-day count in the statistics. Railroad bridges are not inspected by county and state road inspectors.

Is this a train bridge that goes over the Black Prince Creek as it goes into the St.Joe river? Or is this a people and auto bridge? I am trying to find an aerial view photo of the old train bridge over the Black Prince Creek as it flows into the river. Not far from there is a very very old abandoned saw mill high up overlooking the river. Does anyone know the original name of this sawmill?
