And China made it happen; the World longest bridge Completed

China has announced its completion of the world’s longest sea bridge on after its lighting system was installed and tested. It took six years preparation, and eight years to build the 55-kilometre-long bridge linking Hong Kong, Zhuhai and Macao.

It will cut travel time from Hong Kong to Zhuhai down to 30 minutes from 3 hours.
Major work on the bridge consisted of a 22.9-kilometre-long main bridge, a 6.7-kilometre-long tunnel and an artificial island off the bridge, which is considered the most technically demanding part of the whole construction.Zhu Yongling, director of the management bureau of the bridge has confirmed that the bridge will open at the end of the year.

The bridge used 420,000 tonnes of steel which is enough to build 60 Eiffel Towers.
It bridge's total length is 55 kilometres (34 miles) making it 14 miles longer than the distance from Dover to Calais.
The bridge has cost some HK$ 112 billion (£12 billion).

In the next few weeks, engineers and constructors will test the coordination of the bridge’s various systems and equipment, and proceed with inspection and cleaning work, said Zhang Jinwen, project director with the Hong Kong-Zhuhai-Macao Bridge (HZMB) Authority.

“The bridge will be put into trial operation after its port project is completed and taken over by customs, inspection and quarantine, and border control authorities,” Zhang said.
Yin Haiqing, a leading engineer on the project told Xinhua: 'Due to lack of experience, it took us 96 hours to lay the first tube in the ocean and many engineers and workers hardly slept for four consecutive days.'
However it hasn't all gone smoothly.

In the past 14 years, the regional economy and transport network have undergone tremendous changes, leading authorities to re-assess the utilization rate of the bridge, said Su Yi, assistant to the chief of the HZMB Authority.

But Su dismissed worries that the bridge would not have enough traffic, saying, “we have full confidence for the future,We have a whole toolbox of policies at our disposal,” Su said. “It is like playing cards. We can adjust our moves accordingly.”

The bridge will slash travel time between Hong Kong and Zhuhai from three hours to just 30 minutes, further integrating cities in the Pearl River Delta.

Moreover, since the construction began, it has recorded the death of seven workers and one hundred and twenty nine injured ones. Most of them undergo the accident maybe from slipping or felling from a high point. Now the construction is over and its a thing of joy not only for China but also the whole World.
