A gantry spanning the motorway with blue overhead signs showing the following text.
Forward destinations: The NORTH, Scotch Corner A1(M).
Exit destinations: A59 Knaresborough, Harrogate [Airport symbol] York.
Junction number: 47.
The airport in question is Leeds/Bradford again, as part of a signage strategy that sends you down any road vaguely heading that way in the absence of there being one particularly good one.
