New York's Metropolitan Transportation Authority is digging an artificial cavern for a future Second Avenue Subway stop below 86th street. Patrick Cashin is photographing the massive operation. Fortunately, the tunnel has been blessed by a Catholic priest. Check out more of Cashin's photos on Flickr and a brief riff on the project by Geoff Manaugh at BLDGBLOG.
