While Santiago Calatrava’s soon-to-bo-soaring transportation hub at the World Trade Center is just not starting to rise from the ground, the Port Authority of New York and New Jersey has given us a glimpse of what’s been going on underground, complete with the classic articulated ribs that make Calatrava’s train stations so dynamic. And look at all that marble! Sure beats your standard New York City subway stop. This view is actually part of the east-west connector that will eventually be lined with retail shops.
