U.S. Steel Tower, also known as the Steel Building (formerly the USX Tower) is the tallest skyscraper in Downtown Pittsburgh, Pennsylvania, and the 35th tallest in the United States. Completed in 1970, the tower has 64 floors to 841 ft (256 m) and has 2,300,000 square feet (214,000 m2) of leasable space. Its original name was the U.S. Steel Building for many years before it was changed to USX Tower in 1988. The name was finally changed back to the U.S. Steel Tower in January 2002 to reflect U.S. Steel's new corporate identity (USX was the 1990s combined oil/energy/steel conglomerate).
