You know where this is and what is it?

At first I thought it was one of the Jade statue but I already completed all 12. It doesn't look like the HP statues from its silhouette. I've been going nuts circling around that building without any entry. The only entry is the broken part of the overpass and there's already a dead end there. Anyone got hax to see what's on that minimap blimp?
