THE VOLUNTEER pedestrians made at least three crossings of the structure, marshalled across in tightly controlled groups at brisk walking pace. During the third mass crossing, the volunteers were halted at midspan and then restarted.
Readings from accelerometers along the structure's three spans were monitored by WS Atkins, technical adviser to the London Borough of Southwark and the Corporation of London, and Professor David Newlands of Cambridge University, for the Millennium Bridge Trust.
Although the results are still being scrutinised and more tests using mechanical shakers have not been ruled out, subjective assessments of the performance were universally favourable.
Structural engineer Arup and the client are still hoping the bridge will re-open within weeks.
