Santiago Calatrava Discusses the WTC Transportation Hub

In this additional scene from our interview with Spanish architect/engineer Santiago Calatrava, the designer discusses the monumental timespan and demanding criteria of his transportation hub for the World Trade Center. Following Calatrava’s aesthetic calling card, the project’s ribbed vocabulary and “birdlike” form features a 355-foot-long operable Oculus - a "slice of the New York sky" - that casts a soft glow onto the pristine white surfaces of the interior. New areas of the building opened to the public this summer, with the project slated for a grand opening this December.
