Wobbly no more

Lord Norman Foster's elegant lateral suspension pedestrian crossing over the Thames, the Millennium Bridge famously had to shut down days after opening in the year 2000 due to oscillations that were causing the bridge to wobbly to a frightening degree. (The reaction of a friend of mine, who is an engineer, to this debacle was "they shouldn't let fucking architects design bridges".) Eventually they came up with a solution that involved stringing some really big elastic bands and that seems to have done the trick.

Yesterday it passed its most rigorous test so far when 600 people on Spacehoppers bounced across it. I'd say we can believe it to be safe now.
