Dey Street Passageway

The Dey Street Passageway or Dey Street Concourse is an underground passageway in Manhattan, New York City, as part of the Metropolitan Transportation Authority's Capital Construction Program and as part of the Fulton Center project to rehabilitate the Fulton Street complex and improve connectivity in Lower Manhattan. The Dey Street Passageway lies under Dey Street in Lower Manhattan between Broadway in the eastern end, and Church Street in its western end.

During the planning stage of the Fulton Center project, there were numerous alternatives for a passageway connecting Church Street and the Fulton Street complex. These alternatives included a pedestrian tunnel, with a paid transfer, under Fulton Street. Various configurations within the Fulton Center main building were also planned, including a diagonal link between a tunnel under Dey Street and the A C trains mezzanine in the Fulton Center transit hub. The Fulton Center design changed very frequently during planning, but after much analysis, it was decided that a 40-foot (12 m) wide tunnel was to be built under Dey Street, without a paid transfer between the Fulton Street complex and the Cortlandt Street station.

The MTA's decision to disallow a paid transfer was on the premise that Broadway and Church Streets are critical north-south streets. An unpaid passageway would allow non-passengers to move throughout Lower Manhattan, without having to cross those streets. Furthermore, the passageway is planned to directly connect the World Trade Center Transportation Hub, the connection to which opened in the World Trade Center site in May 2016. It is also planned to connect to the other World Trade Center buildings, as well as a new passageway to the World Financial Center.
