What is even more amazing is that this mimics nature. Most trees have a root structure that is a rough mirror image of what's above ground!
The roots are generally much closer to the surface than the canopy is to the ground. Like within a meter versus dozens of meters.

Woah. The water mains are 800 feet down? How does that work? How did they even get there?
It's closer to an underground version of an aqueduct than to a normal water main, a long-distance tunnel being bored to bring water from upstate reservoirs: http://en.wikipedia.org/wiki/New_York_City_Water_Tunnel_No._... I'm not 100% sure why it's that deep (and can't seem to find a solid explanation). What I can glean suggests that it's partly due to wanting it to be in more geologically stable bedrock that passes b…
The greatest depth shown in that graphic is 800 feet. At 10-12 feet per floor, that's equal to the height of a 67-80 story skyscraper. This means Manhattan has a 'mirror-image' city under the ground -- its 'citizens' are electric power, water, gas, and trash. I can't help but be in awe.
This isn't accurate for the entire city. At Astor Place, you can look through the sidewalk grates directly onto the tracks.
Well, of course. The subway system varies in depths from above-ground to hundreds of feet in the ground (I think Roosevelt Island, on the F line, is the deepest subway station).
So, there are two of those deep underground water tunnels, one which runs down from the Bronx through Manhattan and another that runs from the Bronx through Queens and Brooklyn. These tunnels were completed in 1917 and 1935 respectively. How they managed to do this then is beyond me. Currently a third tunnel is being built and apparently it's "the largest construction project in New York history". The project was beg…
What are those tunnels and whats the purpose behind them? Also -- why so deep -- 800ft? I think (and may be wrong) digging them shallower would be cheaper. 6B vs f.e. 4B -- that's a lot of cheddar. Also, someone mentioned "garbage" being underground citizen. I think that's wrong. While we have water, electricity and sewage running underground, the fact that garbage is not a part of this rail is really dissapointing.…
It's true. Roosevelt Island has an underground network of "trash-sucking tubes".
