What is the Millennium Bridge in London?
The Millennium Bridge is a steel pedestrian suspension bridge over the River Thames in London, linking St Paul's Cathedral with Tate Modern. It opened in 2000 and became known as the Wobbly Bridge.
The bridge was designed by Foster and Partners, sculptor Anthony Caro and engineering firm Arup. It was the first new crossing over the Thames in central London for more than a century.
On its opening day in June 2000, thousands of people crossed the bridge, and it began to sway. The movement was caused by people adjusting their steps to the motion, which made the swaying worse.
Fixing the wobble
The bridge was closed two days after opening. Engineers added dampers to absorb the movement, and it reopened in 2002 without the wobble.
The Millennium Bridge offers views of St Paul's Cathedral, the City of London and the Thames.
The bridge appeared in the film Harry Potter and the Half-Blood Prince, in which it is destroyed by Death Eaters. It is a popular route for walkers between the north and south banks of the river.
