The R772 as currently included in TM takes a contrived route between junctions 13 and 14 of the N11. There is a short section of the R772
signed connecting the N11 to the L5067, but there are absolutely no R772 signs pointing along any of the other roads shown.
There is a map of Irish local roads available
here, which indicates that the unsigned sections of the route are actually local roads. In fact, the Newtownmountkennedy end is even
signposted as the L1063! Some of the included sections are also of
very low quality, far below what is expected of a regional road. None of the route (including the signed section) between the two points appears to be legally defined as the N11 by the national government, but the signed section of the route has not been given a local road number, indicating that Wicklow County Council treats it as a regional road.
A point on the R772 at the junction with the L5050 (complementing the one I requested yesterday on the R761) would also be useful, but I'm not sure if it violates 1PPI since much of the traffic using the junction is heading for N11 junction 13.
