"Northway" was originally planned to be an extension of the M12 into the centre of Craigavon, but like many parts of the planned town, it was not built. Close to Portadown town centre, the A4 branches off towards Dungannon and Maghery, and the A3 continues to the city of Armagh, bypassing the village of Richhill.
