example of metropolitan route marker ... in johannesburg. The M indicates metropolitan. It's blue because this is a motorway, and the N indicates North.Originally uploaded to Coppermine on Apr 12, 2007 by michaelsa
Here is a typical gantry sign in South Africa - at one of busiest motorway intersections - indicates how the lanes will split at the point of intersection !! Not necc the lanes at the time. Very clear. Also note route numbers ... N1 would be used for example for the whole stretch of national route one - here it happens to be motorway, but could also be freeway. M1 is the metropolitan motorway running direct through Johannesburg - not a national road!Originally uploaded to Coppermine on Apr 12, 2007 by michaelsa
