The District Department of Transportation uploaded a large set of historical photos of Washington to its Flickr page today, and they’re well worth a look. (The shot above is of the intersection of F and 13th streets NW in 1970.) More photos will be coming in the future, DDOT officials say.

As you might expect for a collection of pictures sitting around a transportation agency’s archives, a lot of them are aerial photos of D.C. streets and highways. But they show how much the city’s physical layout has changed—or hasn’t changed—in the 50 or 60 years since many of them were taken.

(If you’re interested in old photos of D.C., the Library of Congress has some other good collections available, as well.)
