Silverstein Properties has already completed below-ground work on 3 World Trade.

NEW YORK CITY-The third World Trade Center tower planned by Silverstein Properties Inc., for which below-ground work is already complete, may soon land the anchor tenant that would enable SPI to tap into financing pledged by the Port Authority of New York and New Jersey and thus complete the project, the New York Post reported Wednesday. In an interview with the Post, Mayor Michael Bloomberg said the developer is closer than anyone realizes” to signing an anchor.

Citing unnamed sources, the Post said that anchor is likely to be GroupM, a division of WPP Group PLC. GroupM would consolidate its Manhattan operations by taking about 550,000 square feet at 3 World Trade Center, which is planned to reach 80 stories and 2.8 million square feet. Law firm White & Case reportedly is also looking at space there. A spokesman for SPI told GlobeSt.com the firm has no comment on the Post story.

Bloomberg told the Post that the planned 2 World Trade Center was “way down the road. You’d have every building but 2 going.” SPI topped out the steel on 4 World Trade Center at 72 stories this past spring. Click here to read the Post story.
