The South African National Roads Agency Limited (Sanral) has told Parliament that it expects to forgo R10.1-billion in revenue in the coming year because of its inability to enforce revenue collection for its ill-fated electronic tolling project in Gauteng. Sanral was briefing Parliament’s Portfolio Committee on Transport on Thursday afternoon amid several challenges facing the agency, including the cancellation of billions of rands’ worth of tender awards and bottlenecks in getting procurement going.
