Dubna apartment block. Thanks again to Flickr user mixtara for determining the location!
Sequentially I believe it is just after the raketa boat, and just before a walking path along the Moscow river that has walkers and bicyclists.
Taken by my grandfather David C. Cook on a visit to Moscow for a meeting of the International Electrotechnical Commission. Development stamp is June, 1969. Scanned from an unlabeled Kodachrome slide numbered 28 in a box labeled "Russia."
