The last time I saw this building it was a real bus terminal, with the buses situated behind it. How things have changed here. Now it serves as the entry to a modern office building.
From Streets of Washington http://www.streetsofwashington.com/2010/07/washington-deco-old-greyhound-terminal.html with a picture of how it used to look: “The stretch of New York Avenue between 11th and 12th Streets NW is a wonderfully open urban space—a broad, divided east-west avenue with a triangle of parkland and busy north-south streets on either side. The spot could make for a handy transportation hub, and that is just what it did for almost half a century, hosting the Greyhound Bus Lines Super Terminal on the south side of the avenue. Thanks to the valiant efforts of the D.C. Preservation League, the Art Deco Society of Washington and the Committee of 100 on the Federal City, the former terminal, completed in 1940, survives today nearly intact as the entrance pavilion to a modern office building at 1100 New York Avenue.”
