Correct. I had originally hoped the middle tower would be suspended by some elaborate poured-in-place concrete truss system that we'd be eye-level with from the elevated traces South of the site, but that's not the case
In this screengrab from one of my photos, you can see quite a few columns already in-place (particularly the one smak in the middle of the frame), and other caisson top awaiting the columns to grow from them.
Then there's this rendering that further puts those hopes to rest. But if you look close, it does appear there may be some fun concrete or steel acrobatics happening within the interior support structure of the glass cube-like structure. Time will tell...
