Installation of Calatravas Pre-Cast Arches BeginsJul 13, 2008
Last week Port Authority crews began installing the first of approximately 60 steel arches that frame the World Trade Center (WTC) Transportation Hub’s “east-west connector.” The contoured arches are a signature of architect Santiago Calatrava’s hub design, which uses variations of the white arches throughout the 800,000-square-foot hub interior. Pre-cast off site, the arches are staged on the WTC perimeter. Crews then use a crane to set them in place along the pedestrian concourse, which abuts the southern wall of the Freedom Tower.
Meanwhile, on the west side of the site the Port Authority is demolishing the temporary PATH station structure that once opened onto Church Street. That demolition began last week and continues through approximately early August. The new long-term temporary PATH station entrance was moved to Vesey Street at West Broadway in April 2008.
