RN21:
*what's the importance of ArmSom?
Oh, what's the importance of all the wps for dirt roads in the middle of nowhere just to avoid a 10 miles distance between visible waypoints....
ArmSom is the northernmost street of the build-up area heading to Real de San Carlos.
*CarCon -> Con (street name not signed)
RadHer for Radial Hernandez, the village where the junction is, not where the crossroad leads to.
*move Def north one block to Sol, signed as a truck route
*GIS shows a two-block jog on Paraguay in northern Carmelo for locally maintained 21. Signs show northbound traffic turning left on Ansina and right on Italia. There is a similar sign at Paraguay but none for the right turn from Paraguay. Southbound traffic has no signs for the turns shown on OSM, but Google's route is signed. Here's how I'd show the route:
12Feb http://www.openstreetmap.org/?lat=-34.003337&lon=-58.286086
Sol http://www.openstreetmap.org/?lat=-34.001754&lon=-58.285711
Ans http://www.openstreetmap.org/?lat=-33.989452&lon=-58.282900
The exact routing is sometimes a guess in URY. OSM + GM show the same route and that's how I've drafted it. I keep the wps as-is (only moving Def to Sol) - between the one-way streets because I think it is accurate enough.
*add CEduIra http://www.openstreetmap.org/?lat=-33.980494&lon=-58.290807 at the other end of the truck bypass and +X571192 http://www.openstreetmap.org/?lat=-33.958454&lon=-58.319035 for shaping
No C for Calle in CEduIra and visible wp AveNep instead of +X571192
*RioUru has no signed name and is not necessary for spacing
Yep, the new AveNep is enough for the area.
*the bypass of Dolores is locally maintained and not signed as 21 at either end, merely as a truck route. There are signs downtown. The only difference from what GIS shows as the locally maintained route northbound is that signs use Dr. Victor Bertullo instead of Manuel Oribe. Southbound signage agrees with GIS, using General Fructuoso Rivera. So here's how I'd handle Dolores:
GM also indicates the route through the town. I only add the RN96 wp, the rest would be even more guess.
RN22:
*RN106 -> Mig? I cannot find any signs for (locally maintained) 106 south of 54
Will revisit it later when I'll deal with RN106.
RN24:
*remove NueBer; traffic to Nuevo Berlin is signed via RN20_W
But I would need a shaping point instead. Keep as-is since it looks important enough.
*TresQui -> SanJav_S
Keep name of village where the junction is, see above.
RN25:
*I cannot find any 25 shields on the locally maintained portion east of Guichón. So unless I'm missing something, RN90_W -> RN90 and delete the rest.
OSM + GM indicate the route. Keep as-is.
