The city says this is a key pedestrian connection. I suspect this was done without city permission. I will find out. This is not okay. Is this a Jawl building?
Depends if there is an easement/Statutory Right of Way registered for the Yates Centre pathway. Yates on Yates has an SRW agreement that stipulates it is open to the public between 7AM-10PM, but that agreement only covers 1.22m of the future walkway located on their property. They also have to install black security gates at either end.
FWIW, VicMap does not show an easement on the Yates Centre property.
