Remember the 'slinky'? It was a memorising toy that in the form of a steel spring that could climb down stairs. Well that was in the 1970s and along with the children that played with them the slinky has grown-up.
It is now a bridge frame and has been awarded the Steel Innovation award for 2012.
The artist Tobias Rehberger conceived 496 spirals with a diameter of 5m creating a bridge 406m long. The celebrated engineering office of Schlaich Bergman and Partner made it stand in a ribbon configuration with a central span of 66m.
