Pedestrian Tunnel Taking Shape at World Trade Center
By Carl Glassman
POSTED MARCH 2, 2009
Progress can be seen all around the World Trade Center site these days. But one of the most dramatic strands in that complex web of development is 60 feet below street level and hidden from view. It is the shopping mall and shortcut known as the “East-West Connector.”
When the Port Authority completes it, the retail-lined concourse will connect the new PATH station, designed by Santiago Calatrava, with the World Financial Center in Battery Park City.
Atop the tunnel, other workers are constructing a sheet metal roof that will be the base of an extended Fulton Street.
The columns on the north side of the concourse will frame storefronts for some of the half-million square feet of retail space in the transportation hub and office building lobbies—about the same amount of retail the Trade Center housed.
The concourse, now half finished, is expected to open along with the PATH station in early 2014, if the Port Authority can stay on its latest schedule.
