zafr: South Africa Main Provincial Roads

[yakra]

RTR25:
795(N2) -> 795(N1W)?
798(N2) -> 798(N1W)?

The systems seems to be ready for peer-review for a while now. It has 58 routes for about 10,110 miles.
We currently have five travelers.


@Duke87 Do you plan to peer-review the system anywhere down the road as you already reviewed zafn back then?

[shiggins]

I’d like to try peer reviewing this system, if that’s alright. This will be my first peer review, so I welcome any advice or criticism if I’m doing something wrong.

I’d also welcome any good sources – primary or otherwise – if si404 or anybody else knows of any. For the first few routes I’ve started reviewing, I’ve mainly been using their Wikipedia pages, a government document from 2012 titled South African Numbered Route Description and Destination Analysis (henceforth referred to as the RDDA) which is the principal source cited on those Wikipedia pages, and – above all – Google Street View. There are obvious downsides to these sources: The RDDA is now 12 years out of date, and signage visible on GSV is sometimes deficient (particularly – I’ve noticed – in and around Johannesburg, which also happens to be where the highest density of routes is).

In addition to pointing out errors, I plan to give options for replacing shaping points with visible points, wherever I can find a convenient intersection, and to provide a potential name for said new points. I’ve also begun my review under the assumption that we want a point at every Metropolitan Route because they may get added to TM eventually, as briefly implied in the zafn thread.

R21:
N1: Exit is numbered as 134, albeit based off of N1’s exit number.
N12: Exit is numbered as 429, albeit based off N12’s exit number
Consider a point where R21 turns at the intersection of Rietfontein Road and Rondebult Road.
ComSt: Commissioner Street is M46.
There’s a ramp from eastbound Commissioner Street (M46) onto R21 just west of LeeRd.
LeeRd: Should be LeeSt.
M43: Should this be M43_S? Exit 41 would be M43_N if not for the exit number.
Wikipedia, OSM, and the RDDA say R21 then runs concurrently with M43 southwest to N3, but there are no signs indicating this. so I think the route we have is correct.
R22:
Man: This point is not at an intersection, but it is just south of one.
MseAir: Signed as D1885.
Mse: Signed as P444.
+X789427: You could swap this for a visible point at D852 without moving it much.
Mbo: Signed as P446/748. (Also, it should be “Mba” if named after the town.)
D675: D675_N
+X470579: Could be replaced with a visible point a bit south at D675_S.
P746: Signed as P476. OSM appears to be wrong.
+X562592: You could swap this for a visible point at D540 without moving it much.
+X971823: You could swap this for a visible point at P2-8 without moving it much. Also, this is the only KwaZulu-Natal Main/P Road intersecting R22 currently without a point.
R23:
Wikipedia says R23’s northern terminus is at M57. The RDDA says R23’s northern terminus is R21. (The latter is what we currently have in TM.) Signs at R21 and at Monument Road say R23 continues north toward M57. The signs at M57 say that R23 does not reach M57.
+X588400: Could be replaced with a visible point at 8th Ave/7th Road.
M45: Should be M45_N. M45 is concurrent with R23 until Celia Nestadt Road, which does not currently have a point.
MainRd: Main Road is M44.
Missing points at M56_N (Lancaster Road), M56_S (New Kleinfontein Road), and M46 (Airport Road) between SnaRd_N and N17.
R546: R546_S
R24:
Oli: Should be 3rdAve.
+X715393: You could swap this for a visible point without moving it much, but I don’t know what you’d name it. I don’t know what the name of the road is at that curve, but it’s rather illogically signed for Hekpoort, so you could name the point Hek. Alternately, Google Maps says the vicinity of that intersection is called Maanhaarrand, so you could name the point Maa.
+X758929: Another good candidate to be replaced by a visible point at the road just to the north. Said road is the third in under 12 km signed for Hekpoort. Good luck with naming this one.
M36_E: Should be M36. M36 runs concurrently with R24 east from this point to Barratt Road, which currently does not have a point.
MainReefRd: Should be MainReefRd_W.
Missing a point at M67 (Cortlett Avenue) between R558 and CroDr.
CroDr: Should be WilSt.
M18: Should be ComRd. Commando Road is not M18.
Consider adding points where R24 turns at New Castle Road.
Missing points at M5_W (Du Toit Avenue) and M5_E.
R41: I think the eastern terminus of R41 is wrong. While the route we have in TM matches Google Maps and Wikipedia’s route description, the RDDA and OSM have R41 following Marshall Street and Anderson Street to Simmonds Street, and then becoming R29. Signs on Sauer Street (one block west of Simmonds) match this latter routing, and I couldn’t find any signs matching the former. Therefore, this point should be MainReefRd_E.
N12_E: Should this be N12(420)?
R21: Exit is numbered as 46, albeit based off R21’s exit number.

R25:
Unless there’s a recent truncation I’m unaware of, the western terminus we have for R25 is way off. It actually starts at the intersection of M27 (Jan Smuts Avenue) and Cotswold Drive.
M54: Should we split this point into two? The sign for the ramp leaving R25 eastbound has M54 in parentheses, and then there is another sign preceding the next intersection which has M54 without parentheses. The western point could be JohRd, and the east could keep the M54 label.
KwaRd: Should be M86.
There’s a 29.09-mile stretch between R104 and R544 with no visible points. Consider adding a point near Sokhulumi.
Ela: Should be D1399.
Aqu: Maybe should be replaced with a point at the intersection with D2535 just to the north.
R26:
R54: R54 may not extend through Villiers. I’ll have a write-up of the evidence when I get to R54.
+X634073: Could be replaced with a visible point at the next intersection to the south with S1245 and T2368.
+X607213: Could be relaced with a visible point at the next intersection to the south with S1141.
Sla: Should be S1047_N.
+X427459: Could be replaced with a visible point just to the north at S1047_S.
Peka: Should be S306.
ChuSt: Should be S331.
S330: R26 has an overpass over S330. The point should be moved to the next intersection south and renamed to PietRetSt.
Dip: Should be MulSt.
R702: Should be R702_E (or R702_S).
Consider adding a point at the intersection north of R726, since all southbound traffic on R26 heading for R726 would turn there. It should probably be named LucMajSt or ToR726.
R27:
R45: May not be R45 anymore, though it’s still signed for R45. I’ll have a more complete write-up of the evidence for and against R45’s rerouting when I get to R45.
Missing a point at an interchange completed in late 2019 north of LanRd. It’s signed for R45. I’ll have a more complete write-up of the evidence for and against R45’s rerouting when I get to R45.
There’s a 24.03-mile stretch R315 and R307 with no visible points. Consider adding a point at Silverstream Road.
M14: Should be M14_S
PaaEllRd: Should be PaaEilRd.
R27Cal:
+X867477: You could swap this for a visible point at Jimmy Connan Road without moving it much.
+X222608: You could swap this for a visible point at this road signed for Keiskie without moving it much.
You could break up the 30.11-mile stretch with no visible points between R357_Nie and AalSt with a point at this road signed for Gemsbokrivier.
R28:
R93_E: Should be 9thRd. R93 doesn’t exist.
R93_W: R93 doesn’t exist. Should probably be KhoEaHlaAve.
Hil: Should be D1114.
MosRd: Should probably be M1. Signed as M1 and mentioned as M1 in the RDDA, but it’s clearly not the same M1 listed on Wikipedia’s list of Johannesburg Metropolitan Routes. At the next intersection south, it’s signed as M59 (with a very old looking sign), and it was previously simultaneously signed as both M1 and M59 on different signs at the intersection with R28. This is also clearly a different M59 than the one listed on Wikipedia. The road is signed consistently as M1 from Faraday Boulevard south, and signs in Vanderbijlpark mention other Metropolitan Routes, so it seems Vanderbijlpark and Vreeniging have their own system of Metropolitan Routes. The RDDA also says that M1 intersects R28 a second time somewhere along its concurrency with R553, but I could not find any signs indicating this.
VanRieSt: Signed as M4.
R42/R82: Should be R82.
