Why Did The Wobbly Bridge Wobble?

When the Norman Foster-designed Millennium Bridge opened in 2000, it became immediately known as the “wobbly bridge” because of the extreme wobbling sensation felt. For two days, people came to stand and wobble on the bridge which connects St Pauls Cathedral with Tate Modern on the South Bank. And then it was closed and work was set about to make the wobbly bridge less wobbly.

Eight years later, a team of civil engineers claims to have identified the cause of the wobbling: it’s the way that humans walk, naturally moving from side to side rather than in a straight line.
