Gentlemen, Start Your Tunnel Boring Machine

More than 6 stories underneath 2nd avenue, a massive 50 ton Tunnel Boring Machine has started its slow march south from 92nd Street to 63rd.  The link above to Second Avenue Sagas has some great pics and video that Ben shot at the official ceremony last Friday.

I've posted before about the Launch Box for the TBM and now, it's on its way....chewing up a dozen yards of earth a day as it makes it's 30 block journey south.  The downtown tunnel will arrive at 63rd Street in December of 2011 and then they will go back and do the uptown tunnel.  Trains will be running in 2016 and, of course, we'll believe that when we see it.  But this is a huge step forward in the long-delayed expansion of the NYC subway.
