[Tagging] River crossing grade

[Sinus Pi]

> Stepping stones are not a bridge

So when does a structure built to facilitate dry-foot crossing become a
bridge? I'm sure you'll agree that a plank thrown over a stream is a
bridge. A handful of sticks and logs thrown into the stream, like a beaver
dam, surely comprises a makeshift bridge, does it not?
