Here’s a neat old postcard view of Riverside Dr. from the 1950’s. It looks like you can see Belle Isle off in the distance in this one, and I think the shot is looking east from somewhere around where the end of Reaume Park is today.
As you can see in this aerial view from 1949, Reaume Park is brand spankin’ new, and built on reclaimed land. Note in the back ground of the postcard, how natural the shoreline is behind the the car…
Looking at the two photos, I’m not sure that is the same location, however not too far east of the area in the photo, Riverside Dr. moves away from running right next to the river, and west of here, the area around the Ford Plant was still fairly built up.
So… Your guess is as good as mine. With the changes to the shoreline over the years, the exact location may never be known…
