Public sector sources are a major source of funding for transport infrastructure projects. The UN ESCAP estimates that 65% of infrastructure projects in developing countries are funded by government budgets, with the remainder coming from private sector, multilateral development banks, and official development assistance. Governments can fund projects through borrowing, bonds, or equity positions. Specific public funding sources include user fees, taxes, debt, and pension funds. Zimbabwe's dualization of the Beitbridge-Harare Road demonstrates successful public sector funding, with 132km completed using toll funds. Key lessons include the importance of economic stability for projects and utilizing local contractors and resources to save costs.
