Yes, the information presented to me was confusing. I was under the belief that part of the hotel facilities in Aqua and the Swissotel facilities would be linked more substantially than a tunnel, with new facilities under the Aqua pedestal. Looking at the diagrams, this doesn't make a lot of sense. I won't hesitate to say that I'm confused about what they are saying is going on with this point.
That said, yes, you'd pretty much have to walk east to the Swissotel before you could walk west down the pedway that currently exists. This has bothered me since I've started investigating it. Rather than conjecture about it, I have asked a Magellan official and am awaiting reply. I'll post as soon as I get something. It would be great to know more about exactly how the residential, hotel, retail and pedway are all going to be linked together or if all this talk about a pedway link is really something far more disappointing than we would hope for. Sorry for the misleading facilities info above.
All that said, I have just discovered something very interesting on their LSE map. It seems to be on the website too and I can't say how long this information has been out there since I never noticed it before. But, there are in fact five walkways which appear to be two pedway links under Columbus and three more to the north. It seems all five are pedway links given that the two across Columbus don't fall where the current sidewalks exist and run right across the drawing of the medians. One runs from Aqua to the West while the other runs from the south end of the pedastal towards the Fairmont. The other three are very short and almost not noticable. One exists at both the NE and NW corners of the Aqua building supposedly connecting the Swissotel and the 303 building. Yet a third runs from just off the NE corner of the pedestal to the north. Given the confusion about the Swissotel, I'd have to strike my understanding of that connection until fact is handed down from the developer. The discovery of these apparent pedway links is nontheless facinating and a good point of debate from this point. Here's a quick link to their online map which shows the five supposed "pedway" extensions.
