When the new footbridge over the Thames opened, we all flocked to have a go. Unfortunately, human traffic set up vibrations in the bridge that forced its closure. Could it be fixed and what exactly was the problem?

Adam and his team investigate what went wrong. Wobbling bridges aren't new, so why did this one produce huge shock waves among the engineers? Were our walking patterns to blame? What would have happened if cars not people crossed the bridge?

First broadcast: Friday 2 Nov 2001 on BBC TWO
