The M12 is a short motorway spur near Craigavon.
It starts on the M1 to the north of Craigavon city centre. This junction is a modified roundabout interchange: the four slip roads meet at a small roundabout on the southern side of the M1, thus making it appear as though there is a roundabout on the mainline of the M12. This layout is due to the fact that the junction was built with only east-facing sliproads - the others were added later. However, according to signage, the west-facing sliproads are indeed sliproads whereas the east-facing sliproads are the mainline of the M12.
From the roundabout, the M12 heads southwest to go over the B2 before bending to the left (remarkably sharply for a motorway) to a junction with that road, in the usual form of a roundabout interchange. The motorway then loses its central reservation and becomes S2. Then - and only then - does the road lost motorway status. The road ahead, the Kernan Loop, has no given number but leads inextricably to the A3 so may well be a spur of that road.
