civil engineering in China

The Challenge: How to construct overpass over a busy high speed rail track in Wuhan city. Traffic cannot be halted and overpass has to be 256m long weighing 17,000 tonnes spanning 11 rail lines. Engineers in China built the overpass outside the rail lines and rotated it 106 degrees on a 15 metre axis to position it above running trains and it took just 90 minutes.
