On the opening weekend, over 150 000 people use the bridge. On Saturday, larger than expected movements are experienced as larger crowds cross the bridge.
|12 June 2000||
The bridge is temporarily closed to assess the deflection problems that occurred in the first days of opening.
|22 February 2002||
After addition of dampeners during a £ 5 000 000 repair program, the bridge re-opens to the public.
The structural problem of the Millennium Bridge is due to "synchronous lateral excitation", where the footfalls from pedestrians create lateral movements in the bridge. These movements are enhanced when the pedestrians attempt to compensate and match their footfalls to the bridge's movements. At more than 156 pedestrians this type of movement increased visibly in the Millennium Bridge. The structural problems were studied at the Cambridge University Structure Laboratory.
