Engineering consultancy WSP has incorporated technologies that compensate for the potential longer time span between maintenance interventions for the rehabilitation of a 27 km section of road in Gauteng, says WSP director Marshall Muthen. The project, set to begin in January, involves a section of road starting at the D483/P6-1 intersection, close to Bapsfontein, in Ekurhuleni, and ending at the D483/D713 intersection in Cullinan, in Tshwane.
