The link road connecting the M50 at J3 Turnapin to the R139 at the Clonshaugh Road roundabout is currently included as part of the R139. Although this road was
never legally part of the R139 (instead being a
spur of the N50), it was formerly signed as such. However, around 2018, the
signs at the Clonshaugh Road roundabout and on the
link road itself were changed to blue signs with the M50 number, despite the road not technically being a motorway. However, the
signs at the Turnapin roundabout still say R139, although there are M50 signs after this. Should we add this road as a spur of the M50 or leave it as is? I am leaning more towards the former as there are signs in both directions as well as legislation supporting it.
(EDIT: Just in case you aren't aware, motorways in Ireland are legally national roads, not a separate system from them)
