N50 is the statutory name of the M50 in Dublin. It was the only National road to have motorway status throughout.
Between the openings of the M50 Western Parkway, and the southern section, a short section of road linking the Tallaght Interchange and the R114 at Firhouse existed, numbered N50 and not under motorway regulations.
In 2012, the N50 picked up two non-motorway spurs: the former N1 between Kilmore and Whitehall and the former M32. Both of these, plus a short section of road between the R131 and City Interchange are non-motorway.
As with most of the numbering changes in Dublin, the signs are being replaced very slowly, and the former N1 still has no signs of its own but a large N1 sign at each end.
