A-road fork sign
A green sign with a diagram showing an exit branching off the road ahead and the following text.
Forward destinations: The NORTH; Doncaster A1 .
Exit destinations: Newark; Lincoln; A46 [Hollow triangle diversion symbol]; Sleaford; A17 [Solid square diversion symbol].
Winthorpe Interchange is an incredibly busy hub for the trunk road network in these parts - the A1 and A46 cross, plus the A17 starts here. But the junction itself is still, largely, the very modest junction built in the 60s for a much less busy road to Lincoln.
