A green sign with a diagram showing an exit branching off the road ahead and the following text.

Exit destinations: Wideopen A1056 [Solid triangle diversion symbol]; Newcastle (North); (B1318) [Solid square diversion symbol]; Gosforth; Park [Racecourse symbol] .

Wide Open can also be spelled Wideopen, as it is here. Presumably the people who live there don't mind.
