The N4 is one of southern Africa’s strategic freight corridors, carrying trucks that move goods to and from Maputo and across South Africa’s industrial heartland. The announcement of TRAC N4 upgrades is good news for the trucking sector, as any improvement to this road directly boosts fleet efficiency, safety and turnaround times. It also makes it easier for passenger vehicles to share the route with heavy-duty trucks. Keeping this artery reliable is central to supporting both local supply chains and export competitiveness.
According to Trans African Concessions (TRAC), concessionaire of the Maputo Corridor, it remains committed to maintaining the N4, strategic transport route, to world-class standards. To keep the N4 safe, efficient and reliable, TRAC continuously invests in infrastructure upgrades and maintenance.
This includes routine pavement rehabilitation and strengthening, as well as larger-scale projects such as road widening, new interchanges and bridge construction, says TRAC.

Editor’s comment: For the trucking sector, these upgrades are more than just tar and concrete. They represent a commitment by TRAC to a safer, faster and more predictable corridor that links South Africa’s industrial hubs to the Port of Maputo. Every minute saved on this route improves delivery cycles, reduces diesel burn and cuts downtime. TRAC’s long-term investment is not only about smoother transport but also about giving fleet operators the confidence to run tighter schedules and keep exports flowing.
