Re: Footbridges on Keltney Burn exiting Glen Lyon hills

The line cutting across the tributary is in fact part of the O.S. symbol for a run of pylons. (They don't place the actual position of the pylons on the 1:50s, but do on the 1:25s.)

I think they place the descriptor where it has least effect on surrounding mapping.
