GM was sent the photo above from a resident. It is an aerial view of the Georgetown waterfront before the construction of the Whitehurst Freeway. It is likely from around 1940.
The photo comes from the B&O Railroad Historical Society, which would be interested in the Georgetown waterfront since the B&O used to travel right down Water St. and K St.
The photo is a stark reminder of how much different the waterfront was just a generation or two ago. (Rosslyn is similarly changed).
