Update: See the progress of demolition in mid-August of 2021 and was complete by October.
The demolition of the Queeny Tower is proceeding, and when I stopped by on the last Saturday of June, the Caterpillars were working away moving debris around.
Part of the top of the tower is clearly gone, and they are working slowly and carefully to demolish one floor after another.
Pretty much every building along Kingshighway now is from the last twenty years.
