It is clearly not a suspension bridge or something with ropes holding it up so that it can be quickly "cut".

So, your point is what, exactly? That Tolkien wrote aobut the bridge being cut, but then drew a bridge that didn't look as though it could be cut in order to get his real point - that the bridge was not cut - across?
And you talk about us having faith!
