Incredible 11,000-ton bridge detaches to complete 90-degree turn

Incredible footage shows engineers rotating a section of enormous overpass as part of a project to merge ten towns into one mega city in central China's Hubei province.
Workers and engineers made the section rotate 90 degrees yesterday in just 72 minutes.
The elevated bridge is multi-functional, allowing cars, pedestrians and trams to pass through.
Video, uploaded by CGTN, China's national broadcaster, showed the experts carrying out the rotation on May 23.
The section weighs around 11,000 tonnes and has a length of 100 metres (328 feet) with a width of 24.1 metres (79 feet).
It was located on Zuo Miao Road at Donghu New Technology Development Zone in Wuhan City.
Wang Wuli, project manager, told Hubei Daily that the rotation speed was operated by computers.
Wang explained that the rotation didn't cause any disturbance to traffic or rail travel.
Experts took 72 minutes to connect the two sections with a mere one foot gap inbetween which will be filled by concrete mix later on.
According to Hubei Daily, the section on Zuo Miao Road plays an important role in the plan of urbanising the mega city.
