There are two sets of unusual scaffolding set up. One at the A3 end of the

Why build scaffolding around nothing? They are not trying to support
buildings, but have built a huge scaffold for no real reason.

Any ideas?

This is just a guess, but the OS map shows power lines crossing the A3
just west of the hotel. Is the scaffolding beneath these power lines?
If so then there's some maintenance going on on the pylons and the
scaffold is related to this.
