Despite the negative impact of its recent tender cancellations, South African National Roads Agency Limited (Sanral) says it continues to improve, manage and maintain the national road network. In Limpopo, the R37 improvement project between the Modikwa mine and Burgersfort worth R616-million is under way. The project involves widening the road, providing overhead lighting and constructing four major structures and a pedestrian bridge. The existing drainage structures will also be lengthened and upgraded to accommodate the widened road profile, says Sanral communications and marketing GM Vusi Mona.
