The tallest building in my town is 5 stories. Imagine that. Just 5 floors. You could probably sprint to the top floor in under 2 minutes. The tallest building in Chicago Illinois is 110 floors. Slight difference… and there probably isn’t any sprinting to the top.
Formally known as the Sears Tower, the Willis Tower has stood proudly in the heart of Chicago since the 1970’s. The building took 3 years to complete with the help of around 2000 workers. The building has some impressive statistics: the amount of concrete to make the building could pave an eight-lane, 5 mile (8 km) long highway, 25,000 miles (40233 km) of plumbing fill the building, 1500 miles (2414 km) of electric wiring snakes it’s way around the building and lastly there is 80 miles (128 km) of elevator cable.
