Jiaozhou Bay Bridge


Hi friends,

Sorry for a long gap. Due to various works I was not able to visit my blog such a long time. And with this post, I now end the thirst for knowledge in civil engineering in you. Many might be aware of this post but for those who are unaware of it can be benefitted by this post.

The Jiazhou Bay Bridge, world's longest ever sea bridge constructed by China is our topic today. Let us see more informations about this bridge. The Jiaozhou Bay Bridge is a T-shaped bridge connecting the three important places in China, Huangdao District, the city of Qingdao and Hongdao Island. The bridge which was opened on 30th June 2011, reduces the travel distance between Qingdao and Huangdao.Here is the view of Jiaozhou Bay Bridge from top showing the connection made between the trios.








The overall length of the bridge is 42.5 kilometers. Now here is the interesting thing about the bridge. The construction was started by three groups of engineers and workers. The first group started to construct the bridge form the Huangdao district, another group commenced their work from the Hongdao island and the third group's starting point was the Quigdao city. Now if there was any error in the construction of any one of these groups then there are chances of this like distortion.






The mistake that has not been commited during the construction of this bridge in China, was commited in Brazil during the construction of a sea bridge. This shows how much the engineers are careless. It has resulted in the wastage of large amount of money.




How hilarious this bridge looks? Its quite surprising to see these and we really wonder how the engineers and architects who were part of these constructions must have reacted seeing them.

However this mistake was not commited during the construction of the Jiaozhou Bay Bridge in China. Some of the other facts are below.

It used 450,000 tons of steel and 2.3 million cubic metres of concrete to take its shape. The human force involved the construction was 10,000. The bridge is designed to withstand a severe earthquake, typhoon and even collision of ships. The bridge has six lanes and two shoulders.
