Slurry wall work is active along Liberty Street

As part of the September 2006 agreement to rebuild the World Trade Center site within six years, Port Authority of New York and New Jersey crews are hard at work constructing permanent slurry walls that will form the "bathtub" on the east side of the site. The work consists of excavation, utility relocation, and slurry wall construction along Church Street and the future restored Greenwich Street (between Vesey and Liberty Streets).

The project involves careful coordination with other construction taking place in and around the bathtub, including that of the new WTC Transportation Hub and the Dey Street Pedestrian Concourse, which will link the Hub to the Fulton Street Transit Center by 2009. Structural work also is necessary around the 1 train tube, located under Greenwich Street in the center of the site, forming the bathtub's western edge.

The bathtub construction began in late summer 2006, when the Port Authority agreed to complete the sites for Towers Three and Four (from Liberty to Dey Streets) by late 2007 and the Tower Two site (Fulton to Vesey Streets) by mid-2008. Upon their completion, Silverstein Properties will take over the site to build all three towers by 2012.
