The same reason the millennium bridge broke- feet landing at the same time will cause the bridge to sway one way and then when the other foot comes down the weight is transfered so the pressure causes the bridge to sway the other way eventually causing a disaster (only works with some types of bridges so don't get your hopes up) -I think p.s I'm only in yr 7 at school so I'm not entirely sure

Why do soldiers break their steps while passing over a bridge?
In theory, a number of people marching in step can set up vibrations that will cause a bridge to collapse. It may only be an urban legend, but our DI said it was true, so we always "broke step" when crossing the bridge from Recruit Island to the main base. On 12th April 1831 about 70 men from the 60th Rifle Corps, had been carrying out exercises on Kersal Moor and were returning to their barracks by the way of a suspension bridge across the River Irwell in Lower Broughton. As they crossed the bridge it began to vibrate with their step and as the vibrations increased with more soldiers on the bridge, the suspension chains snapped and the bridge collapsed, throwing the men into the water. As it was, the river level was quite low and there were no major injuries and no lives were lost. It was never clear whether the accident was a result of the vibration caused by the marching men or inferior engineering, however, since then the order has been given to break step whenever the military cross a bridge.

Why soldiers are told to not march while crossing abridge?
Harmonics. Most bridges are strong enough to support the weight of soldiers marching in lock step, but the constructive vibrations still hasten the need for repairs. Harmonic vibrations induced by the wind brought down the Tacoma Narrows Bridge, "Galloping Gertie."
