"In January 2004, Santiago Calatrava unveiled his design for the World Trade Center Transportation Hub: a new, permanent facility for Lower Manhattan, located immediately to the east of the original World Trade Center Twin Towers. The project replaces the original Port Authority Trans-Hudson (PATH) rail system that was destroyed on September 11, 2001. In addition to serving the Port Authority Trans-Hudson (PATH) commuter trains, the building also connects to New York City subway trains (1, A, C and R lines); to provide seamless, indoor pedestrian access to Brookfield Place, towers 1, 2, 3 and 4, as well as the new Fulton Street Transit Center; and creates an inspiring, light-filled public gathering place."
