When it opens in 2014, the Fulton Street Transit Center will connect eleven lines (not counting PATH trains)—more than any other station in the NYC subway system. It's currently budgeted at $1.4 billion (fun fact: the original budget was $750 million!), but it hasn't received nearly as much press as the World Trade Center rebuilding going on just a block west, or the Santiago Calatrava-designed PATH station slated to go up on Church Street. That's a shame, since hundreds of thousands of people use the station every day, and all of them will see their commutes shortened and made more pleasant once the construction in completed. We took a tour this morning of the ongoing work—click on to take a look at some of the highlights of this massive project.
