What I found on Superior Street by the Greysolon Plaza

That is much concrete and plastic pipe that will be used in the second phase of the Superior Street reconstruction.  The Greysolon Plaza that was once the Hotel Duluth is in the background.

I wonder what the workers who used mostly hand tools that first cleared Superior Street out of a hillside forest would have thought of these big construction vehicles.  I can only wonder what construction machines will be used to rebuild Superior Street in the next century.
