The Willis Tower (formerly named, and still commonly referred to as the Sears Tower) is a 108-story, 1451-foot (442 m) skyscraper in Chicago, Illinois.[4] At the time of its completion in 1973, it was thetallest building in the world, surpassing the World Trade Center towers in New York, and it held this rank for nearly 25 years. The Willis Tower is the tallest building in the United States and the fifth-tallest freestanding structure in the world, as well as the fifth tallest building in the world to the roof.
The Sears Tower observation deck, called the Skydeck, opened on June 22, 1974. Located on the 103rd floor of the tower, it is 1,353 feet (412 m) above ground and is one of the most famous tourist attractions in Chicago. Tourists can experience how the building sways on a windy day. They can see far over the plains of Illinois and across Lake Michigan to Indiana, Michigan and Wisconsin on a clear day. Elevators take tourists to the top in about 60 seconds. The Skydeck competes with the John Hancock Center's observation floor a mile and a half away, which is 323 feet (98 m) lower. Some 1.3 million tourists visit the Skydeck annually. A second Skydeck on the 99th floor is used when the 103rd floor is closed. The tourist entrance can be found on the south side of the building along Jackson Boulevard.
In January 2009, the Willis Tower owners began a major renovation of the Skydeck, to include the installation of glass balconies, extending approximately four feet over Wacker Drive from the 103rd floor. The all-glass boxes allow visitors to look through the floor to the street 1,353 feet (412 m) below. The boxes, which can bear five short tons of weight (about 4.5 metric tons), opened to the public on July 2, 2009.
You can stand outside the edge of the tower 103 stories up in these clear boxes!
Just to say I did.
