The M20 south of Limerick.
The M20 is the motorway standard section of the N20 south of Limerick. It runs from a junction with the M7 and the N18 to the diverge with the N21.
Since the 2000s, there have been vague plans to extend the motorway to Cork, forming an 'Atlantic Corridor' motorway network that doesn't radiate around Dublin. These proposals became formal plans in October 2017.
