A green sign with an arrow pointing diagonally up and left, and the following text.
Stibbington.
We're on a section of the A1 that was dualled a long time ago, and which has a lot of low-standard junctions with local roads and some fairly sharp turns. It also skirts very close to the village of Stibbington, which is just on the left. There's even a warning sign for a school here.
