Abstract:
Developing countries face inadequate resources for funding road infrastructures. This has 
amalgamated the public and private sectors into a mutually beneficial relationship through 
Public Private Partnerships (PPPs). Although extensive documentation exists on PPPs 
globally in various sectors, studies examining the challenges to PPPs in Road Infrastructure 
Construction projects in Tanzania are inadequate. This study aimed to address this 
shortfall. Purposive sampling was used to select 20 respondents for the study. A qualitative 
research design was used in the study, and data were collected through semi-structured 
interviews, focus group discussions, and document reviews. Thematic analysis was 
employed to analyze the data from interviews and focus group discussions. Over two-thirds 
of the interviewed respondents revealed that lack of preparedness, limited information on 
available opportunities for PPP projects, and inadequate capital market were among the 
main challenges facing PPPs on road infrastructure projects in Tanzania. The study calls 
for improving the institutional framework to enhance private sector participation in PPPs 
in road projects.
