Trans African Concessions (Trac) says traffic volumes are steadily increasing on the N4 between South Africa and Mozambique after South Africa moved from Alert Level 5 to Alert Level 4 and then on to Level 3 in its programme to battle the Covid-19 pandemic. Trac manages the N4 toll route starting from Solomon Mahlangu offramp, in Tshwane, to the Maputo Port, in Mozambique. “The lockdown requirements, when initially announced in March, had a direct impact on traffic across the country, since only essential service traffic was allowed to travel,” says Trac communications manager Solange Soares.
