The Jersey Tunnel

The price tag for this rail tunnel that Governor Christie doesn’t want to build under the Hudson River strikes me as a not-unreasonable sum of money to lay out in exchange for the benefits at hand. Certainly compared to the cost of what we’re doing in Afghanistan, it looks like a very smart investment. But I don’t actually understand why the price tag is so high—we have all these other tunnels into Manhattan and I don’t think they cost nearly that much.

But then again I’ve been here in Israel and Palestine and not reading up on the issue. So who wants to leave links in comments that explain it to me?
