What material is the Millennium Bridge made of?
The main materials used in its construction are concrete, steel and aluminum. About two platforms steel support three sections of 81m, 144m and 108m, from north to south were assembled. The cover is aluminum with 4 m wide and lined with steel railings.
What type of bridge is the Millennium Bridge?
Suspension bridge
Millennium Bridge/Bridge type
Structurally, the bridge pushes the boundaries of technology. Spanning 320 metres, it is a very shallow suspension bridge. Two Y-shaped armatures support eight cables that run along the sides of the 4-metre-wide deck, while steel transverse arms clamp on to the cables at 8-metre intervals to support the deck itself.
What caused the Millennium Bridge to wobble?
It has generally been thought the Millennium Bridge ‘wobble’ was due to pedestrians synchronizing their footsteps with the bridge motion. The researchers found, to their surprise, that pedestrians walking randomly, keeping balance as normal can cause large bridge sway.
How was the Millennium Bridge engineered?
Built using ‘lateral suspension’, an engineering innovation allowing suspension bridges to be built without tall supporting columns, the Thames’ newest crossing was hit by a phenomenon called Synchronous Lateral Excitation when loads of people flooded over its shiny new deck.
Who built Millennium Bridge?

What went wrong with the Millennium Bridge?
The bridge opened on 10 June 2000, two months late. Unexpected lateral vibration due to resonant structural response caused the bridge to be closed on 12 June for modifications.

Who fixed the Millennium Bridge?
Arup announced this week that it had had corrected the fault to the Millennium Bridge, but warned that other pedestrian bridges may have to be adapted to prevent them wobbling. The bridge’s tendency to sway by up to 75 mm in each direction, has been reduced to a few millimetres by fitting dampers at a cost of £5m.
How long was Millennium Bridge closed for?
Swaying Millennium Bridge to close after two days.
How much did it cost to fix the Millennium Bridge?
Repair work to the swaying Millennium Bridge across the River Thames in London will cost an estimated £5m and take six months. Engineering firm Arup is planning to attach a “shock absorber system” to the £18.2m structure, which closed in June due to excessive movement when used by crowds of pedestrians.
