Hey, it's the Big Dig! The picture shows a multi-level buried road. Pedestrians walk on the surface, shopping and going to restaurants. Then there are two buried levels for cars (a slow-level with parking, and a deeper fast-moving level for through traffic), and below all of that the subway, with elevators to/from the surface.
Thanks! I especially like the allusion to the Big Dig. When I moved to Boston in 2000 or so, I got use to being in cars where the driver would suddenly start screaming, "Where's the road? It was here yesterday!".
