 Route Step, MARCH (Posted on 2005-04-16)
In the Military there is a long standing tradition that you do not march soldiers over a bridge in step. When marching and approaching a bridge the command of Route Step, MARCH is given. This command keeps the soldiers marching in formation, but every soldier is allowed to march at her/his own step. Although this is widely practiced in the Army, I found very few who knew the reason why.

What could have possibly prompted this tradition?

 Submitted by Bruce Brantley Rating: 5.0000 (1 votes) Solution: (Hide) The reason is the possibility of the bridge collapsing. There are many stories of bridges that collapsed due to soldiers marching across them. It is possible for this to happen due to the resonant frequency of the bridge. Much like the high pitch that can cause a glass to shatter, marching at a rate that causes vibrations at the resonant frequency of the bridge can cause it to collapse. There are several excellent examples in the comments and Juggler offered a very interesting alternate theory.
