A green sign with a diagram showing a roundabout with exits ahead, left and right, and the following text.
Forward destinations: The NORTH; Peterborough A1 .
Left turn destinations: Old; Warden .
Right turn destinations: Biggleswade; A6001.
The next section of the A1 is one of the oldest lengths of dual carriageways on the whole route and is bristling with side turnings and private property accesses - a big step down from the sort of thing you expect on the A1.
