Hmm. It sounds like the IKEA will be shut down for a while. It would seem that the IKEA needs to move out before Sears can move into that space. Then the Corbeil will be moved. Only then can the old building be demolished and the new one built.
The out-buildings should not be affected.
I am interested to know what improvements they plan for the road network. And how they will get back the lost parking.
