In and around Birmingham I've noticed several instances where a towpath bridge over a side arm has one of its parapets clad in corrugated iron sheeting.
I guess that the modification is to make it more difficult to climb on, thus protecting neighbouring properties from trespass. It's a shame that a historic structure has to be defiled like this.
