Motorway fork sign
A blue sign with a diagram showing a branch off the road ahead and the following text.
Forward destinations: [Solid triangle diversion symbol] Carlisle; Penrith .
Exit destinations: ; Shap; (A6).

The two carriageways run some distance apart for several miles as we climb up here to Shap summit. We're in an extremely high, exposed location now, and in winter conditions here can be bleak.
