The accelerating pace of global urbanization and climate change has positioned sustainable infrastructure engineering at the forefront of civil engineering practice. Traditional construction methodologies, while addressing immediate infrastructure needs, frequently fail to meet long-term sustainability and resilience requirements. This paper presents a comprehensive review of sustainable infrastructure engineering, examining the integration of environmentally responsible materials, energy-efficient designs, advanced digital technologies, and resilient structural systems. Through analysis of current practices, innovative technologies, and case studies, this review demonstrates that sustainable infrastructure requires coordinated efforts among engineers, urban planners, and policymakers. The paper highlights key advancements in green materials, circular economy principles, smart infrastructure systems, and climate-resilient design. Findings reveal that sustainable innovations not only reduce environmental impact and optimize resource utilization but also enhance structural adaptability and community resilience. This review concludes that the future of civil engineering lies in the adoption of regenerative design principles, digital transformation, and holistic life-cycle management approaches that benefit both environmental and socioeconomic dimensions of infrastructure development.
