A-road cantilever sign
A green sign suspended over the road from a post on the left showing an exit coming up, and the following text.
Forward destinations: The NORTH, Peterborough A1 [Hollow circle diversion symbol].
Exit destinations: The MIDLANDS (M1, M6); Kettering A14; Huntingdon A141 [Solid triangle diversion symbol] [Solid square diversion symbol] [Hollow square diversion symbol] [Solid circle diversion symbol] [Solid cross diversion symbol].
I think this is National Highways' entry for the "most diversion symbols on one sign" award.
