Millennium Bridge, London people walking caused small sideways oscillations in the bridge, which in turn caused people on the bridge to sway in step, increasing the amplitude of the bridge oscillations and continually reinforcing the effect. On the day of opening, the bridge was crossed by 90,000 people, with up to 2,000 on the bridge at any one time. Resonant vibrational modes due to vertical loads (such as trains, traffic, pedestrians) and wind loads are well understood in bridge design. In the case of the Millennium Bridge, because the lateral motion caused the pedestrians loading the bridge to directly participate with the bridge,
London Bridge Is Falling Down children in the foundations of the bridge was first advanced by Alice Bertha Gomme (later Lady Gomme) in "The Traditional Games of England, Scotland and Ireland" (1894–1898) and perpetuated by the usually sceptical Iona and Peter Opie. This was based around the idea that a bridge would collapse unless the body of a human sacrifice was buried in its foundations and that the watchman is actually a human sacrifice, who will then watch over the bridge.
