Motorway fork sign
A blue sign with a diagram showing a branch off the road ahead and the following text.
Forward destinations: London; Hatfield.
Exit destinations: Ware; Stevenage; A602; [Solid diamond diversion symbol].
Junction number: 7.
In common with all New Towns, Stevenage has something of a fetish for roundabouts. It might be one of the UK's better laid out and more successful experiments in urban planning.
