Giant, heavy bridge turned in world first

Check out this feat of engineering as an enormous, heavy bridge is turned around.

A?bridge, weighing 33,000 metric tons,?was swiveled around an angle of 42.3 degrees to dock with other bridge sections on Thursday in Tangshan, North China's Hebei province.

Swivelling a bridge of this size and weight?marks a global first.

A spherical hinge, the major piece of equipment used to turn the bridge, set world records in carrying-weight capacity and size.

The diameter of the hinge is 5.5 meters.?
