It was on PBS either last Wednesday or Thursday on Nova I believe. That is the same project. They are boring the tunnel through an existing station and are actually boring at 13 inches above an existing tunnel and 30-something inches below the escalator structure in the station. They refer to that section as "the eye of the needle." I'm amazed they could do it without damaging anything.
