N4 toll concession

This case study examines the N4 toll road, a 30-year infrastructure PPP between the governments of South Africa and Mozambique and the private consortium Trans African Concessions. The project, valued at approximately $466 million, connects Witbank in South Africa to Maputo in Mozambique, serving as a critical export link and a route for labor migration.

• The N4 toll road project was valued at approximately $466 million and is structured as a 30-year concession, after which ownership of the infrastructure will return to the governments of South Africa and Mozambique. Financing was provided through private equity and loans from major sub-continental financial houses, primarily in South Africa, with additional funding from a mine workers pension fund and the Development Bank of South Africa. Both governments provided debt guarantees to ensure loan servicing if Trans African Concessions was unable to do so.
• The project faced significant political and bureaucratic barriers, including a leadership change in Mpumalanga province that created a political vacuum and opposition from local road users in South Africa. Bureaucratic challenges included complex treasury regulations, high staff turnover in government leading to a loss of institutional memory, and slow decision-making at the municipal level due to the frequent use of "acting" mayors and CEOs. These issues resulted in delays in obtaining environmental authorisations.
• To address affordability and social tensions, the project implemented a tiered pricing schedule with higher fees on the South African side than on the Mozambican side, and granted reduced rates to local residents. The private partner also launched information campaigns in English and Portuguese to combat misinformation and built a formal market for informal traders, although the market's management by local authorities has been described as poor.
• To reduce cargo congestion and cross-border bottlenecks, a one-stop border facility is planned at Komatipoort/Ressano Garcia with an estimated cost of US$ 20 million. However, progress on this facility has slowed due to a lack of financial resource allocations from both South Africa and Mozambique.
