In our every day lives – particularly as commuters – we probably cross a number of bridges every day.
But there are some bridges in the world that are far more exciting than others. From a bridge that the Devil himself is said to have helped build, to a bridge that curls up, structure analysis software providers Oasys cast an eye over some of these unique structural successes.
1. Germany ‘s Devil’s Bridge
This bizarre bridge, combined with its own reflection, creates a perfect circle. The bridge is said to have been commissioned by a knight in 1860. But the rocks and stones used for its creation are jagged and spikey, so it was dangerous to cross.
According to Earth Trekkers, there were other Devil’s Bridges built in the past as a masonry challenge. The idea was that only Satan himself could help with a difficult build such as these bridges, and the first human who crossed the completed bridge would pay for the Devil’s helping hand by giving up his soul.
Today, the bridge is off-limits for preservation reasons. But it is still an oddly beautiful sight to behold!
2. India’s Living Roots Bridges
These bridges are a testament of patience and adaptability. These beautifully natural bridges were formed by guiding rubber tree roots with hollow canes so that they would grow outwards and meet from either side of a stream. It would take years to reach the opposite bank, but the hard work paid off as these Living Roots bridges can support the weight of a human.
They were originally made by the Khasi tribe, who realised the bamboo bridges they were building would collapse or rot after a monsoon or heavy storm.
3. The Rolling Bridge, found in the UK
Created by Heatherwick Studios, the Rolling Bridge is a steel bridge that covers an inlet in London. What makes this bridge so unique is that it can tidy itself away!
When needed, this bridge curls up into an octogen shape to stand on one side of the canal until a boat passes. The bridge also curls up every day at noon, if you want to see it in action!
4. Norway and the Da Vinci Bridge
This bridge was originally designed nearly 500 years ago by Leonardo Da Vinci, with the intention of being built across the Golden Horn in Istanbul. The original drawing had a single span of 240 metres, but the project did not go ahead as it was believed that such a design was not feasible.
But the bridge was brought to life in Norway, as the first example of a major engineering feat to be built from a Da Vinci drawing. The bridge has just three arches to support the structure. Though the Norwegian bridge is a smaller version of the original plans, it shows that the design works — one arch under the bridge, and two arches either side leaning inwards to spread the weight.
5. Vietnam’s Dragon Bridge
Located in Da Nang in Vietnam, the Dragon Bridge is certainly a spectacular sight! The bridge is the result of an international competition by the Da Nang People’s Committee in order to improve travel in the city. The bridge has six lanes for vehicles, two lanes for pedestrians, and 2,500 LED lights.
Incredibly, the Dragon Bridge is fully capable of breathing fire too. In fact, the bridge can spout water or fire, and this display is often used for special occasions in the city.
