A green sign with a diagram showing a roundabout with exits ahead and right, and the following text.
Forward destinations: Edinburgh A1; Berwick (A698).
Right turn destinations: Scremerston; A1167 [Solid triangle diversion symbol].
This roundabout (the first since Bedfordshire) marks the start of the Berwick Bypass, and you'll notice it also marks the point at which our final destination appears on the signs.
