Investment in physical infrastructure, such as roads, bridges, airports, sea ports, water ports, railways etc., is a fundamental ingredient in the growth and economic development of a country. Compared to countries like Singapore, South Korea and China, countries in Sub-Saharan Africa have significantly underinvested in infrastructure over the years, resulting in stunted growth. Zambia, which has a large infrastructure funding gap, and a ballooning government debt, cannot rely solely on the government to meet its infrastructure funding needs. This study looked at establishment of a strategic financing mechanism for sustained construction and maintenance of Zambia’s public roads- a case of Lusaka district. The study adopted pragmatism philosophy, focusing on practical, real-world outcomes. It combined quantitative and qualitative methods to address establishment of a strategic financing mechanism for sustained construction and maintenance of Zambia’s public roads (Tashakkori & Teddlie, 2010). A mixed-methods approach was used, integrating both qualitative and quantitative techniques. Qualitative methods (interviews, focus groups) explored strategic mechanism of sustained financing for construction and maintenance of Zambia’s public roads, while quantitative surveys measured ways of sustaining the financing for construction and maintenance of the public roads This approach provided a comprehensive understanding of how to have a strategic mechanism to fund the construction and maintenance of public roads in Zambia (Creswell & Plano Clark, 2017). The study applied both deductive and inductive approaches. Data collected was analysed using the Dedose Software for the qualitative part and for the quantitative part a thematic analysis was used to come up with the results. Zambia has in place legal and institutional frameworks (Tembo, 2015) that are necessary for effective and efficient road asset management. This study established that a number of financing strategies or frame works for road construction and maintenance such as RoadSIP 1 and II and RoadSIP III (yet to be launched), performed fairly well albeit some challenges. It also established that most road projects under implementation are under the government’s balance sheet and that, the Road sector’s indebtedness to local Contractors and Consultants was increasing and the financing gap was widening. Zambia would need to spend an average of $1.6 billion a year over the decade 2022–30 to develop the infrastructure found in the rest of the developing world (Foster and Dominguez, 2010). To close this financial gap required raising more funds and looking for more effective ways to meet infrastructure targets. The study established that since traditional funding methods for road construction and maintenance in Zambia such as tax revenues and loans are becoming unsustainable, there is need to look for other alternatives. The study established the potential strategic sources of funding for sustained construction and maintenance of Zambia’s public roads include public private partnerships, equity financing, road tolls and establishment of a State Infrastructure Bank(s). The study also established a Strategic Road Financing Framework (SRFFW) that clearly illustrates the interconnection between institutional governance, revenue diversification, community engagement, and sustainability. To Address financing challenges, it was recommended that there is need to increase Public-Private Partnerships (PPPs) by inviting the private sector to participate in the construction, maintenance, and financing of roads.
