The old John Jay High School is finally losing its scaffolding. The school on Seventh Avenue in Park Slope–which is actually the Secondary School for Law, the Secondary School for Research and the Secondary School for Journalism–has been surrounded by scaffolding for more than a year as work was done on the building. Yesterday, we noted that work crews are finally removing the metal and wood. We dislike scaffolding and the sidewalk tunnels that it creates, so we’re always glad to see it being dismantled and carted off.
