A blue sign with a diagram showing a branch off the road ahead and the following text.
Forward destinations: The NORTH; Scotch Corner; A1(M).
Exit destinations: Wetherby; (A168); Otley; A659.
Junction number: 45.
If you've arrived here via the M1, the fact that this is junction 45 causes no end of confusion. The M1 counts up to junction 47 and then joins the A1 at junction 43, so you see the same numbers twice in quick succession.
