Underside of bridge from Southbank Millennium Bridge and River Thames, looking north The bridge's movements were caused by a ' positive feedback ' phenomenon, known as synchronous lateral excitation.

The natural sway motion of people walking caused small sideways oscillations in the bridge, which in Milennium park caused people on the bridge to sway in step, increasing the amplitude of the bridge oscillations and continually reinforcing the effect.

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, the vibrational modes had not been anticipated by the designers.

The crucial point is that when the bridge lurches to one side, the pedestrians must adjust to keep from falling over, and they all do this at exactly the same time. Hence, the situation is similar to soldiers marching in lockstep, but horizontal instead of vertical.

The risks of lateral vibration problems in lightweight bridges are well known. The greater the number of people, the greater the amplitude of the vibrations. For example, Albert Bridge in London has a sign dating from warning marching ranks of soldiers to break step while crossing.

Auckland Harbour Bridgewith a lateral frequency of 0. After a period of testing, the bridge was successfully reopened on 22 February The bridge has not been subject to significant vibration since.

In spite of the successful fix of the problem, the affectionate "wobbly bridge" epithet remains in common usage among Londoners.

This used acoustic transducers placed at strategic locations on the cabling of the Millennium Bridge and the signals from those transducers were amplified and dynamically distributed throughout the Turbine Hall of the Tate by a programme which Fontana entered into the sound diffusion engine of the Richmond Sound Design AudioBox.
