Zeerust R49/R47?

Does anyone have an idea what the name of the road leading North out of Zeerust is? Bing and Google say it’s the R49 while OSM and Garmin seem to indicate its the R47. :? Can anyone out there confirm? At this stage I’m leaning towards R49.

Kyle, I’ll go with what the BGS says - some new streetviews : Just outside Zeerust and further towards the border

It is indicated as the R49 in both views.
