The 327-kilometre Lusaka-Ndola dual carriageway project is set to serve as a crucial test case for the long-term viability of concession-based infrastructure projects in developing economies, according to Public-Private Development (PPD) specialist Vicente Valencia.
With a total investment of US$650 million, the project operates under a 25-year concession agreement, comprising three years of construction followed by 22 years of operation. Valencia highlighted that the project’s success will largely depend on toll affordability and traffic volume, both essential factors for its financial sustainability.
Recognized as a major Public-Private Partnership (PPP) initiative, the Lusaka-Ndola dual carriageway has been listed among the top 10 PPP projects to watch in 2025. In his article, “10 PPP Projects You Should Monitor in 2025”, Valencia described it as a flagship infrastructure development for Zambia and a critical indicator of the potential of long-term concessions in emerging markets.
Another notable PPP project Valencia highlighted is Kenya’s Nairobi Expressway, a 27-kilometre toll road connecting Jomo Kenyatta International Airport to Nairobi’s city center. With an investment of US$600 million and a 27-year concession period, the Nairobi Expressway serves as another benchmark for private-sector-led road infrastructure in Africa.
“These projects, including the Lusaka-Ndola and Nairobi Expressway, showcase the transformative power of Public-Private Partnerships in driving infrastructure innovation, stimulating economic growth, and shaping global best practices,” said Valencia. “Beyond their scale and complexity, they hold the potential to set new standards for future PPPs worldwide.”
By demonstrating the feasibility of long-term road concessions, these initiatives could pave the way for increased private sector investment in Africa’s infrastructure development.
