I'm pretty sure it will be raised one more time. They put about 4 sections in, which adds 80' (is that right, Kevin?). But there's at least 150' more to build.
On edit:
Okay, I looked at this a little more closely. Crane sections are normally 20' tall, from what I could gather. In this photo, it looks like there are 2 sections joined together that are being added at once.
The red "expander" section is also about the same height as 2 crane segments.
Just eye-balling it yesterday from the Hilton pool deck, it looked like they added about 4 more of these double-stacked segments, so instead of 80' higher it's probably more like 160' higher.
Say maybe this was the last bump.
