Infrastructure investment is a critical element of driving economic growth, social inclusion, and regional integration. In Jammu and Kashmir, the need for improved road infrastructure has been a critical strategy for enhancing connectivity, pushing trade, and supporting increased tourism in the region. As this study highlights, the state government does not possess the financial capacity or have the requisite resources to fund mega projects due to logistical challenges, financial bottlenecks, lack of capital formation, and administrative hurdles. The present study aims to investigate the role of the Public-Private Partnership as a sustainable financing strategy for road infrastructure in Jammu and Kashmir. By employing a mixedmethod approach integrating primary and secondary data, the study will explore the stakeholders’ perspective, project efficiency, risk implications, and the sustainability aspect of the PPP initiatives in the state. Results established that PPP models significantly improve the efficiency of project execution, equitable risk distribution, and long-term maintenance if supported by policy clarity and transparent and accountable leadership. However, the state grapples with regulatory uncertainties, project withstand attacks, investor apathy, and inadequate government elimination capacity. I implemented this by suggesting policy input, project capacity, and funding topologies to strengthen the PPP process for sustainable infrastructure development in Jammu and Kashmir.
