An earlier scheme, deviating considerably from the current numbering, is described in the 1970 Shell Road Atlas of South Africa and other contemporaneous sources: • N1 - equivalent to the current N9 from
George to
Colesberg, and then the current N1 from there to
Beitbridge (with deviations as some newer parts had yet to be built) • N2 - equivalent to the section of the current N2 from
Cape Town to
Durban • N3 - equivalent to the current N3 from
Durban to
Ladysmith, then following the current N11 to Volksrust, and the current R23 from there to Heidelberg, and then continuing equivalent to the N3 until its end in Johannesburg • N4 - equivalent to the section of the current N4 from
Pretoria to
Komatipoort • N5 - equivalent to the current N5 but from
Winburg past Harrismith to Ladysmith (the latter part now signed as the N3) • N6 - equivalent to the current N6, except that it begins from King William's Town, the section from there to Stutterheim now being the R346, and ending in
Reddersburg. • N7 - equivalent to the section of the current N10 from Ncanaha to just past
Middelburg • N8 - equivalent to the section of the current R64 from
Kimberley to
Bloemfontein • N9 - equivalent to the section of the current N1 from Cape Town to Colesberg • N10 - equivalent to the section of the current R56 between Kokstad and Pietermaritzburg • N11 - equivalent to the current N7 from Cape Town to the Namibia border • N12 - equivalent to the section of the current N12 from George to Beaufort West • N13 - equivalent to the section of the current N12 from Three Sisters to Johannesburg • N14 - equivalent to the section of the current N2 from Durban to Eswatini • N15 - equivalent to the section of the current R75 from Port Elizabeth to Uitenhage • N16 - equivalent to the section of the current N3 between Heidelberg and Harrismith • N17 - equivalent to the section of the current N10 between Noupoort and Namibia • N18 - equivalent to the section of the current R61 from Queenstown to Port St. Johns • N19 - equivalent to the section of the current R56 from south of Jamestown to Kokstad == See also ==
