The New York MTA is in the midst of a “golden era” of tunneling for the New York subway. Three separate mega-projects are currently underway totaling some $15 Billion: The Second Avenue Subway, The East Side Access Project (which features the new Grand Central Terminal), and The Number 7 Subway Line Extension Project. The short video below was published by the NY Post and included in an AP Article. It is tantalizingly short, but gives a great perspective on what the underground construction project at Grand Central looks like and a sense of the scale…the amazing huge caverns being constructed. The article says that from underneath Grand Central Terminal alone, the construction crews have removed enough material to cover Central Park almost a foot deep!
