There are some preview images coming out for The Art of Avatar Fire and Ash book and there are so many cool stuff there but I'm most fascinated by this image as that's likely the Betabridge still under construction. Unfortunately, even this tells us nothing about its purpose.
Betabridge was something were were supposed to see in Fire and Ash coming online. We saw it in the leaked script pages and everything else in those came about. But Betabridge was completely cut out and it just makes me even more curious about what it's supposed to be.
Looking at it in this concept art I want to agree with people who theorized that this will be a base to a space elevator. I could imagine we see its anchor points. Earlier art of Bridgehead shows it to us at earlier stage of construction. We can see it's gigantic and separated from the main city and both of these would make sense for a space elevator anchor site.
However, that leaked script has it come online with a brilliant light and a shockwave. It is described as a combination of oil rig and a nuclear reactor. None of this sounds like space elevator. Space elevator would need a line first. And this is not how you get it to work.
So what else can it be. I saw ideas that it will be a teleportation hub but that seems like to out there for Avatar which tries to stick to more realistic near future sci-fi. I've heard a machine to change the atmosphere but that would be too small and also how would humans deal with all the detritus from dead animals and plants and the climate change.
Not knowing is going to bother me the whole time till next movie happens.
