The M12 was to be an urban motorway serving the new town of Craigavon, burrowing into the town and forming a C-shape, beginning on the M1. This part of it was built along with the M1, and nothing was ever done to finish it. The whole of Craigavon is basically half-built.
The M12 has a questionable start. Motorway restrictions begin halfway underneath junction 2, where the road widens out to dual carriageway. Technically non-motorway traffic can use the road until this point, from which there is no exit.
Junction 1 was originally envisaged to be a three-level interchange. In the 1960s it was opened with east-facing slips only, and a bridge was built over the M1 ready for its completion. In 1992, the junction was finished, but without actually bothering to build a third bridge to complete the interchange - instead using a flat roundabout to connect the three arms. It does look ridiculous, but it's functionally no different from a roundabout interchange - these kick off a number of mainland motorways like the M50 and M180.
Those used to driving on the mainland will probably look twice when they see that junction two connects with the B2.
