A blue sign with a diagram showing a branch off the road ahead and the following text.
Forward destinations: The SOUTH; (M18, M1); Newark.
Exit destinations: Rotherham; Doncaster; A630.
Junction number: 36.
If you're going to Rotherham for heaven's sake don't turn off here. It's served by about a hundred junctions on the M1 and M18, all of which will get you there more quickly than slogging your way through Warmsworth, Conisbrough and Dalton.
