The South End Fitness Center reopened last Wednesday after the last of the displaced homeless residents who occupied it in the wake of the Long Island Bridge failure were moved into the new facility on Southampton St. I went last Wednesday afternoon for my workout and the place was spotless. Everything had been thoroughly cleaned and painted and the gym floor had been refinished. The pool temperature wasn't up to the standard ~80° yet, but depending on equipment and size, it can take up to a couple of weeks for some pools to get to temperature. I'm doing a charity swim in Provincetown next month, so I might take advantage of the cool water there and practice in my wetsuit.
Not sure, but this is a completely different project in a part that was to remain (mostly) unaffected by the tower project. The pool repair project consists of a depth reduction, new drainage system, retiling of the pool and pool deck, and natatorium window replacement. It is expected to be finished in August.
I recently saw a render of a taller iteration of this tower, in the range of 27-30 floors. I can't remember where I saw it but it led me to believe that this isn't dead.
