Transcript of The Royal Gorge Bridge

The Royal Gorge Bridge
History of the Bridge
The concept of the Royal Gorge Bridge was first created in the early 1920's by architect George F. Cole. The bridge was planned to be a pathway across the treacherous Arkansas River. It eventually became a celebrated tourist attraction as time went on. When the final plans and preparations to construct the bridge were finished in 1929, engineers and builders alike came together and started to build it across the wide canyon. It was to be one of the first of its kind to reach as far up as it did. The bridge broke the record for the highest bridge overall for 72 years until it was finally beat out by the chinese Beipanjiang River Bridge, although it was still the highest suspension brige in the world. It was the location of many famous events and even appeared in a Super Bowl Ad! Sadly, the bridge was damaged by recent wildfires and is currently being renovated.
The Royal Gorge Bridge is a suspension bridge that extends 1,260 feet above the Arkansas River. A suspension bridge is a deck that extends over an expanse and is held up by cables which are attached to vertical suspenders. Some famous examples of suspension bridges are the Golden Gate Bridge, the London Tower Bridge, and the Sydney Harbor Bridge.
Suspension Bridge
Like many bridges of its kind, the Royal Gorge Bridge heavily utilizes triangles to support itself. This is because triangles are one of the strongest built shapes and can hold massive amounts of weight. Not to mention that they are very sturdy too. This bridge uses triangles in many different ways. It uses them to support the two towers, to steady the entire bridge, and to reinforce the deck of the bridge. Also, the cable suspension system uses triangles too.
Use of Triangles in the Royal Gorge Bridge
The Royal Gorge Bridge does fit the definition of a suspension bridge. It has a long expanse of a deck that stretches across the canyon. The deck is supported by beams which are attached to tall vertical suspenders.
