The N6 provides a vital cog in the transportation of goods and services between Lesotho and Coega. This popular route, particularly between Smithfield and Rouxville, previously posed significant road safety challenges. The upgrade included widening and partial vertical realignment of the existing road, with fewer blind rises and a longer field of vision for motorists. The road is also being widened to 12.4 metres, with a generous shoulder on each side. SANRAL prioritised pedestrian safety by reducing the speed limit, building sidewalks on both sides, creating safe crossing points and installing streetlights.
