4,000 feet glass bridge above Colorado River
Fear of heights? This is definitely no place for you! 
Skywalk commonly known as The Glass Bridge is one of the aspiring civil engineering project which shows the unmatched thinking of civil engineers. The construction of this glass bridge started in March 2004. Glass Bridge will be suspended 4,000 feet above the Colorado River on the very edge of the Grand Canyon. In 2005, it was tested for its structural ability and the results were really very good. It passed all its engineering requirements by
400 percent and therefore the total load which this glass bridge is
able to withstand is equal to the weight of 71 fully loaded Boeing 747
airplanes which is more that 71 million pounds. The bridge will be able
to sustain winds in excess of 100 miles per hour from 8 different
directions, as well as an 8.0 magnitude earthquake within 50 miles. It
is said that more than one million pounds of steel was used in the construction of the Grand Canyon sky walk. Amazing!
