Work Already Under Way on Third Quarter Milestones That Will Bring Most of Western Half of WTC Site Up to Street Level

The Port Authority today released its latest quarterly milestone report announcing that it has met 19 of 20 second-quarter 2009 rebuilding milestones. Milestones for the second quarter included: the installation of more than 2,400 tons of steel for the National September 11 Memorial & Museum, the equivalent of 20 Statues of Liberty; the installation of 1,250 cubic yards of concrete - the equivalent of six miles of New York City sidewalk - bringing the plaza and main entrance of One World Trade Center to street level; and, competitively bid one of the largest and most critical work packages for the World Trade Center Transportation Hub.

The one missed milestone - Complete Approximately Half of Sector 3A Steel over the PATH Line - is substantially complete and will not affect the project’s critical path.

The bistate agency also announced today that it has begun work to meet 24 third-quarter milestones, which will bring most of the western half of the site up to street level for the first time.

The work completed to date and in the coming quarter will allow 9/11 family members to walk out onto the Memorial Plaza for the first time during this September’s anniversary. The Port Authority is partnering with the Memorial Foundation and the City of New York on the detailed logistics of that day.

The major milestones were established as part of the World Trade Center Assessment, a comprehensive review of all of the major public projects on the World Trade Center site. It was released last October. The Port Authority has since been issuing quarterly reports so the public can track the rebuilding progress and challenges.

Today’s report can be found at

Highlights for the third quarter include: the second-to-last installation of structural steel for the entire 9/11 Memorial; the installation of steel columns that will support the WTC Transportation Hub’s roof over the PATH tracks, as well as a major Hub contract for the construction of Greenwich Street and the permanent support of the No. 1 subway line; and, the completion of the street-level plaza that surrounds One World Trade Center. The report also lists 19 milestones the agency has set for the fourth quarter of this year.

Port Authority Chairman Anthony R. Coscia said, “We’re pleased that the site’s public projects continue to move forward on schedule. We’re already hard at work to achieve milestones for the third quarter and we’re continuing to tackle the rebuilding challenges that lie ahead.”

Port Authority Executive Director Chris Ward said, “The rebuilding is on track and this report tells us we are hitting the milestones to keep it on schedule. But we have some critical milestones coming up so we need to continue working aggressively to make sure we hit each one of them.”

The major milestones met by the Port Authority are:

World Trade Center Transportation Hub:

  • Begin 9A Underpass Excavation for East-West Corridor.
