Drove by the site today. Lots of excavator work from what I gathered. Unfortunately, traffic was moving freely so I couldn't take a pic. One of those cases where I'd welcome a truck blocking the box. That steam pipe btw on the corner of Madison and 42nd is causing mayhem traffic wise. For those that don't know what I'm talking about, one of these bundle of joys.
If possible, avoid 42nd going crosstown.
