Sustainable infrastructure development has become an important strategy in improving social welfare and supporting equitable regional development. This study aims to analyze the impact of sustainable infrastructure development on community social welfare through a literature review approach. The study uses a qualitative descriptive method with a literature review design by examining various national and international scientific sources related to sustainable infrastructure, social welfare, and psychological aspects of society. Data were obtained from journals, books, policy documents, and previous research published within the last five years. The results of the study indicate that sustainable infrastructure development contributes positively to improving accessibility, public services, economic growth, and community participation. Infrastructure development also affects psychological well-being by increasing feelings of security, comfort, social cohesion, and public trust in the government. However, infrastructure development may also create social inequality, environmental problems, and psychological impacts such as social stress and anxiety if it is not implemented inclusively. Therefore, sustainable infrastructure development requires participatory planning, equitable distribution, and integration of social, economic, environmental, and psychological aspects to create inclusive and sustainable development.
