Yup. Surely they could just bridge over the path: it should be perfectly clear that the path continues straight through, and if you stick two sets of doors at either end of an atrium in the middle of it… lots of people will become befuddled...
Looking at the various renderings, I think it's supposed to be wooden slats over glass, sorta like what has been done with the horizontal metal bars on the podium of The One. The parking garage looks to be underground based on the overhead map shown in the article, which shows an entrance tunnel south of the surface parking lot.
Agreed, just move the circulation between the hotel and arena up a level.
The design isn’t even approved yet, so not soon.
As mentioned previously, two years after OverActive Media announced this proposal, they're apparently still clinging to some faint hope of attracting a "50 per cent equity partner" in the project, while they continue to lose millions of dollars. I would guess it's probably going to be Live Nation Entertainment who decide what eventually happens regarding any new construction or rebuilding of a large music venue at Exhibition Place or Ontario Place. If they haven't already bought into OverActive's proposal by now, I would doubt it's going to happen.
I'm curious here as the linked reports say the intent has always been to produce a multi-purpose venue, and they note e-sports is intended to be only a minor, though consistent tennant. They give reasoning that there is a lack of indoor venues of this particular size in the City and expect the facility will be able to be used for any purpose needed. Is that consistent with their design? Could it be used for anything? Which venues would they compete against? Maybe Massey Hall?
