The tower that will be known as 1 World Trade Center has reached the equivalent of the 20th floor.

The Port Authority of New York and New Jersey said Wednesday that the skyscraper is now 200-feet above street level.

The authority said workers are installing 16 steel nodes on the 20th-floor level. They serve as joints between the steel framing for the building’s podium and the steel for the rest of the tower.

Port Authority Executive Director Chris Ward said the progress is a sign that the site is no longer a pit.

The planned 104-story skyscraper is scheduled to be completed in 2013. It will be 1,776-feet from street level to the top of the tower’s antenna.
