Ste. Genevieve County, Missouri
and Randolph County, Illinois
In the 30 odd years I've known about it, this has always been a car ferry. Don't recall any rr tracks crossing the Mississippi here. Be sure to check out Modoc Rock Shelter in Illinois before you go to St. Gen to see the marvelous old town. Ferry itself is small and one that sits low in the water--a bit more scary on the on and off ramps than the one at Cave-in-Rock, Illinois.
Was this one thime a rr ferry ? if it was what rr is it?
