Compiled by the Port Authority of New York and New Jersey.
- More than 1.2 million cubic yards of earth and rock were excavated to make way for the World Trade Center. The excavated material was placed in the Hudson River to create 23.5 acres of new land deeded to the City of New York.
- This landfill area is now Battery Park City.
- More than 200,000 tons of steel, far more than the amount required for the construction of the Verrazano Narrows Bridge, was used in the World Trade Center's construction.
- The 425,000 cubic yards of concrete used in building the World Trade Center is enough to build a five-foot wide sidewalk from New York City to Washington, D.C.
- At peak periods of construction, some 3,500 workers were on the site daily.
- There were 43,600 windows in the Twin Towers with over 600,000 square feet of glass window area. They were cleaned by automatic window washing machines traveling on stainless steel tracks.
- With 60,000 tons of cooling capacity, the World Trade Center's refrigeration plant was the largest in the world.
- The 360-foot television mast atop One World Trade Center supported 10 main television antennas, numerous auxiliary antennas and a master FM antenna. Transmissions from the mast began in June, 1980. Ten television stations in the metropolitan area, including all the major networks, broadcast from the mast. In addition, six stations broadcast high-definition, digital television from the World Trade Center.
- The Tower's skylobby elevator systems separated express from local runs. There were 239 elevators and 71 escalators in the four buildings operated by the Port Authority at the complex. The sky lobby express elevators were capable of carrying 55 people, a 10,000 pound capacity. Express elevators could travel at speeds of up to 27 feet per second.
