The Millenium Bridge is a 330 m steel bridge linking the City of London at St. Paul's Cathedral with the Tate Modern Gallery at Bankside.
|
The bridge has a profile 6 times shallower than a conventional suspension bridge. It is supported by four highly tensioned cables on each side of the deck, anchored at each abutment and propped by two river supports.
|
The bridge was so popular that people crossed it in their thousands at a time, causing it to sway. It was therefore modified with dampers to stop the wobbles Viscous dampers are located under the deck, around the piers and the south landing to control the lateral motions and act much like shock absorbers.
