Route 7 in the northern Virginia suburbs of Washington, DC, is also known as Leesburg Pike. It goes all the way from Alexandria, on the waterfront, to Leesburg, well into the foothills of the Appalachians. It is one of the busiest thoroughfares in the region and has innumerable shopping centers, office and commercial buildings, and residential complexes along its path.
This is a drawing of one of the commercial buildings on Route 7. It currently houses a Mattress Discounters. You can see some vague reflections of the "futuristic" designs of the 1960s in this structure, with its slanted roof and dormer, its solid portico also with a slanted roof at the left end of the drawing, and the stacked up sign, now in disrepair, at the apex of the roof. I drew this on location, ink in sketchbook, about 10" x 7".
