A Fascinating View of New York, From 80 Feet Below

First announced in 1929, the subway is planned to eventually run from the Financial District, at Manhattan's southern tip, up to 125th street, along Second Avenue.  

Working 24 hours a day since 2008, in a process that works much differently now than it did when the first subway was built in 1900, "about 475 laborers are now removing 15 million cubic feet of rock and 6
million cubic feet of soil - more than half an Empire State Building by
volume - out from under two miles of metropolisr," writes Kim Tingley. For all the modern technology, however, "There is still no way to mine a tunnel without sending men into it."

"Underground, they breathe chemical fumes and dust, no matter how well
filtered the air. Water and mud splash up and rain down. They yell
themselves hoarse over the rumbling of machines and don't always wear
earplugs against the din. 'I think the biggest thing I'm sacrificing is
my health,' [sandhog Ryan] McGinty said. 'But for me to do something I love and be
proud of what I do - If I made it to 60, I'd be happy.'"

"The president of M.T.A. Capital Construction Company, Michael
Horodniceanu, has taken East Siders on Saturday cavern tours, in part to
make up for the blasting. 'They're all kind of in awe of what they're
seeing,' he said, 'because they understand that it's been created by
men. The question that I always get: ‘What was here before?' The answer
is, ‘Solid rock.' "
