Those photos from across the river are the perfect complement to the photos I above showing the crane BOOM lifting the rebar.
I would walk by on the sidewalk; but could not see where the rebar went, or what was going on up on the top floors. It is great to see the marvel of the construction from so many different vantage points.
Thanks to JC Heights - and many others - for the great ‘under construction’ photos.
