In Toronto such spaces exist under the Gardiner Expressway west of Spadina Avenue. Some areas are used informally as parking lots while others sit vacant.
With new developments rising next to the Gardiner Expressway, many of these spaces could be reprogrammed whereas in Buffalo, with so much office space unused, new uses for these dead spaces are unlikely.
With the steel beams running into the distance, I find this space intriguing.
This is the third image in a series looking under elevated expressways in Buffalo.
