Check out what's going on beneath New York City

The biggest public transit infrastructure effort in the US is almost completely invisible — unless you’re 160 feet underground. The East Side Access project will connect the Long Island Railroad to New York’s Grand Central Terminal via a massive tunnel under the East River. Actually, that tunnel was the easy part; it was started in 1969. The hard part? “We are building a brand-new railroad here,” says Michael Horodniceanu, president of Metropolitan Transit Authority Capital Construction. When it’s finished in 2019, around 160,000 people will see shorter commutes. But before that, engineers must complete three tricky segments. Here’s how (and where) they’ll do it.

Amazing tool, the human mind.

3. It seems straightforward

Simply remove everything that doesn't look like a subway tunnel.

4. I'm sure they have underground pumps in case of flooding.

But I hope they have some system in mind for stopping flood waters from getting in through the entrances.

After TS Allison flooded the Texas Medical Center in 2001, some of the hospitals there (maybe all, but I can't find that info) installed flood-gates to keep any future flooding out of their basements.
