Chinese workers rotates 8,800 tonne bridge section - YouTube
Amazing time-lapse video shows Chinese workers rotating an 8,800-tonne bridge section for 80 degrees to form a new overpass - while the railway underneath stays open
- The overpass is located near a Train Station in Wuhan, a major Chinese city
- It spans over the nation's busiest railway line that carries 150mn people a year
- Engineers managed to build the traffic link without interrupting any traffic
- The task was done just before Theresa May arrived at the city for her China visit

They managed to build a massive motorway in the middle of the city and above China's busiest railway line - without interrupting any traffic.
Part of the Changqing Road Overpass, in downtown Wuhan, was rotated for nearly 90 degrees during the wee hours to connect with the other parts of the flyover located at either side of the railway.
?The overpass is located near the Wuhan Hankou Train Station and runs above China's busiest railway line, the Jingguang railway. Pictured, bullet trains prepare to set out from Wuhan
Workers first built the section of the flyover parallel to the railway lines and then rotate the structure which weighs a whopping 8,800 tonnes.
The Changqing Road Overpass spans over the Jingguang railway which connects Beijing and Guangzhou, two major Chinese cities.
A spectacular time-lapse video has been released, showing how workers turned the enormous section for 81 degrees clockwise while the railway stayed open during the wee hours of January 31.
The footage was produced by the Chinese Railway Construction Corporation, which is building the motorway. It has been featured on multiple Chinese media outlets, including QQ.com, People's Daily TV and China Central Television Station.

The busy railway tracks underneath were not closed during the construction and rotation
The overpass is situated near Hankou Train Station in downtown Wuhan, the provincial capital of Hubei Province with around 10 million people.
It runs above nine railway tracks, on which some 600 trains run daily.
The Hankou Train Station is a major rail hub in east-central China and a big station along the Jingguang railway.
Running between the Chinese capital city and the provincial capital of Guangdong Province, the 2,284-kilometre-long (1,419-mile-long) Jingguang railway carried 150 million passengers in 2013.
The section of the flyover measures 135.2 metres (444 feet) long and 51 metres (167 feet) wide.
The impressive engineering task was carried out by workers in bustling Wuhan city (pictured)
Wuhan is the first stop of Theresa May's three-day visit in China, which began yesterday
Apart from the section's heavy weight, the challenge of the rotation was the fact that its supporting column is not in the middle, which means the section is off balance.
According to the engineers, the supporting column is about one-third way into the section. The longer arm is about 3,600 tonnes heavier than the shorter arm.
The workers built a second point of support during the rotation to ensure it would run smoothly. They also used a series of toothed gears.
According to China Central Television Station, the rotation began at 3:04am so it would not interrupt rail traffic.
The section was docked into the flyover 103 minutes later.

中國這個新操作太欺負人 又讓西方沒麵子

[環球網報道記者查希]隨著英國首相特雷莎·梅抵達武漢開始為期三天的訪華之旅，武漢的一群中國工人也剛剛完成又一工程壯舉，且這一壯舉在西方國家看來是無法想象的。英國《每日郵報》在2月1日的報道中感慨道，武漢工人在中心城區、中國最繁忙的鐵路線上，架設了一座巨型公路橋，並且這一過程並未影響交通。
報道稱，淩晨時分，武漢市常青路主線轉體橋，轉動接近90度後，順利與引橋實現精準對接。
據《湖北日報》報道，1月31日淩晨3：05，漢口火車站西側咽喉地帶，我國首座極不平衡轉體橋——武漢常青路高架跨鐵路轉體橋順時針旋轉81°，成功跨越京廣、滬蓉、漢丹等鐵路大動脈，實現“完美轉身”。
“轉體正式開始！”1：37，各項準備工作就緒，現場指揮一聲令下，電動機啟動，轉體梁開始順時針旋轉：1：45轉體10°，1：49轉體15°，1：53轉體20°，此後基本保持這一速度；當轉體接近尾聲僅剩最後0.5°時，開始緩慢減速，進入“點動”操作模式；3：05，轉體梁順利精準就位，現場響起熱烈掌聲。監測數據顯示，轉體十分成功。
看到國內媒體的報道，再看英國媒體的描述，我們可以感覺到他們的“羨慕”之情。當然，這樣的文章，讓一些美國網友看到後，也發生了奇妙的化學反應，一言以蔽之：酸。
這位美國網友說：很有趣，但是看上去沒必要吧。
另一位美國網友也表露了同樣的態度：中國是全球建設的領導者，但是其他很落後。
還有一個網友說：會不會出什麽簍子啊？
不過，還是有網友對上述觀點表示反對，稱“西方曾經是科學技術的領導者，但現在確實官僚主義的領頭羊。”
這位網友也說：這要在美國得一個月。
網友jpearson45更直接，“要是在美國，這個作業至少需要8800個機構的批準，然後聽取8800場社區聽證，然後需要8800天才能完工。
這句話顯然刺痛了一些酸民，這個酸民在評論下留言稱，“不過至少我們放心，不會塌掉呀。”
反觀美國，我們連一個暴風雨過後的水坑都填不上。環環：中國速度是我們的驕傲，麵對一些人“恨人有，笑人無”的風涼話，我們大可不必在意。我們完全可以邀請他們來中國，看看中國的變化和發展。

Interesting, but it hardly looks necessary.
