I guess what I am trying to say is, the bridge will essentially function as an entry/exit for the Queens Wharf casino when it should be for a wider public use. The bridge could have multiple entries and exits, not necessary just to the casino itself. It will be great to have it connected to Elizabeth Street, Stephens Lane or Miller Park. But what do I know.^^ It will be foot traffic only - they aren't going to allow any kind of vehicular traffic to zoom through the loads of pedestrians in their busy core dining precinct, especially when that dining precinct is several storeys up with no street level access. It would be akin to allowing bikes or scooters to ride through the Treasury.
The bridge will also have stairs being the main access on the South Bank side (with a ramp provided for PWD access only), so hopefully that will help get across the idea that it's foot traffic only.
