Port Elizabeth - The South African National Roads Agency Limited (Sanral) believes its completion of an R80m slope stabilisation engineering project in Nelson Mandela Bay has saved Africa’s automotive manufacturing capital from power blackouts.
Sanral said in a statement the instability of the R75 on-ramp into Uitenhage was undermining the structural integrity of pylons carrying overhead electrical cables supplying large areas of Uitenhage with power. It has been a source of concern for authorities and industry since 2012 when a part of the slope was damaged by heavy rains.
"Sloughing or erosion problems [of the slope] began in the mid-1980s mainly due to the lack of maintenance. This, in turn, allowed moisture to seep into the slope. Previous methods of stabilisation were not effective as they only dealt with close to surface water or moisture contained within the slope," said Michelle Ah Shene, administrative and communications manager at Sanral.
