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."
Why arn't solgers and bands allowed to march over bridges?
Soldiers and bands break step so as not to reinforce the fundamental vibration frequency of the bridge. For an example of wind reinforceing the fundamental frequency look up the Tacoma Narrows Bridge.

Can a marching army collapse a bridge?
A column of soldiers will never march across a bridge for this reason. The steady oscillation that occurs can, over time cause structural issues with even a well built bridge. It may not actually collapse (although not out of the question) but it can cause serious damage if the marching approaches the resonant frequency. The classic example of resonant frequency that every engineer has had to watch the video of is the Tacoma narrows bridge. There are also many examples that Tesla explained on this subject.
Why are soldiers told to break step or not to march in step while crossing a bridge?
The story is that 20 soldiers were injured when the Broughton Bridge (Manchester) collapsed on April 12, 1831. The cause was determined to be a bolt that sheared off from the effects of mechanical resonance. The impact vibrations from the uniform step of the marching soldiers was believed responsible. In other less famous situations, the same type of physical damage has occurred to other structures.
