This suspension bridge is the longest in the world and is located in Randa, Switzerland. It is built for pedestrian travel in the Alps. The bridge has a length of around 1600 ft. The plus point of this bridge is it is not swinging unlike most suspension bridges.
I have been to Jung Frau and did not see any such thing there. We had the gondola from the railway station that took us up to Jung Frau where we had a walk in the ice palace. – a great memory.
This video is interesting to watch
