This is a corridor on an Imperial Star Destroyer. This design is more simular to that of a corridor on the sith warship, The Harbinger from the game Knights of the Old Republic 2: The Sith Lords. However I wanted to give it a more imperial feel, and I must say I really like the outcome of the design. There are also two decks: the top deck being the main access way and the bottom deck is the maintainence deck. A small band of rebels have escaped capture on board the Star Destroyer after they're ship was tractored to the main hanger bay.
