13. Steel Beams inside The World Trade Center Transportation Hub PATH Station

Skanksa built both the original World Trade Center and the new Transportation Hub, designed by Santiago Calatrava. In the new station, there was a deliberate move to also remember what happened on 9/11. To that end, the design has made visible the sections of the original steel framework and concrete foundation of the Twin Towers. You can see these sections under glass on the platform of the PATH station.
