One Grant Park has begun making its push toward the sky in the South Loop.

One Grant Park has begun going vertical at the south end of Grant Park, and the corner of Roosevelt and Indiana will never be the same. The shiny 76-story, 792-unit apartment tower from Rafael Viñoly Architects is a busy site these days, and you know longer have to stand on tip-toes and peer over the fences to catch the action. In fact, you could pack a picnic and sit amongst those leg-statue thingies and watch McHugh Construction work whilst you dine in the park.
