New York Subway Expansion

The pics are amazing.

Dubbed the 'The Line That Time Forgot,' the Second Avenue Subway has been a New York City dream since the 1920s.
Then came the Great Depression and World War II, followed by lack of funds that stopped the project after several stretches of tunnel with tracks were built in the 1970s. The existing tunnels are now being incorporated into the new ones.
The first phase - 1.7 miles with stations between East 63rd and East 96th streets - is to be completed in 2016 at a cost of $4.5 billion. Funding and plans for the rest of the route are still up in the air.

I thought it was interesting how they freeze the ground in some places to avoid disturbing the buildings above.

Well actually the whole thing is fascinating but I would loved to know how they figured out they could use refrigeration in that way. Perhaps an engineer will come along and explain it to us.
