Yeah, that's what had been throwing me. Now that the blueprints have helped me get past the problem I'd been having while wrapping my head around trying to make buildings in the artwork line up with existing buildings (and now realizing it was because everything in the artwork is a new build or new facades on buildings that don't have them), I'm now taking a second look at the Eiffel Tower in the artwork.
Currently, the tower is on top of the theater building, which is to the left side of the artwork. But the art shows it on the far side of the bakery building, in the space between the bakery and the new attraction building, roughly where the largest backstage building currently sits on that plot of land. My assumption is that they're replacing the current tower with a newly fabricated one that will have the proper scale for its new location.
