As I said above, I think this is a very good design. There's still the question of how exactly it will be linked to Canary Wharf, as the riverside is so badly planned there that there is little permeability, but I'm sure they'll think about that.
From the plan it looks like they've tried to connect it in to the Canary Wharf road system, rather than landing it on the river bank at the lower level?
That's a great idea but I'm not sure the CW group would ever let it happen.
