Because the combined vibrations "build up" and can collapse the bridge.
No, it was American troops that captured the Ludendorff railroad bridge at Remagen on March 7, 1945. It was American troops that used the bridge to cross the Rhine River at that location. The British troops under Montgomery were further north preparing to cross in their offensive sector. Also, this same bridge was used by American, French & possibly British troops after the end of the First World War (in 1918 & 1919) to cross the Rhine River. The bridge was built during the First World War.
The large band could disrupt gravity which can make it very hard for them to cross.
because marching of troops cause small forces(legs) to superimpose into a single large force which causes vibrations and repeated marching provides the resonance frequency and thus it may cause damage to the bridge!
