Follow up from a couple of days ago. I swung by the site of the Green Stairs on the West Side neighborhood. The removal has completed. All I found at the site are the cement stairs and green railing that lead the tower portion.
I also received an email from Carol, formerly of St Paul Daily Photo. She too documented the green stairs with photos. She was able to watch a good deal of the stair removal and took some photos during the process. See her photos here
