You guys heard about this proposed bridge?
-9 miles long
-3 towers which support it are 3000 feet tall each
-combination of suspension and cable-stay
-the base of each tower would be about the size of a football field
-amount of steel cable used to build it: 1 million miles (enough to circle earth 30 times)
-takes 10 years to build (and 15 billion dollars)
saw a special on the discovery channel about it. this is even more astonishing than that huge freedom boat. all of that weight is supported by 3 towers!!! :Q now that is simply a marvel of engineering.
