Although numerous studies have investigated sustainability in construction engineering, assessing sustainability across the entire life-cycle of structures while incorporating environmental, economic, and social considerations is key to enhance infrastructure resilience. Nevertheless, structures and infrastructure systems, particularly bridges and transportation networks, are exposed to damage and disruption from natural and human-made hazards. Aging and deterioration processes, exacerbated by climate change, shorten the operational service life of systems, increase repair and maintenance costs, and adversely impact sustainability. This review paper emphasizes the importance of implementing sustainability throughout a structure's life-cycle and integrating sustainability with multiple performance indicators, including safety, reliability, risk, and resilience based on a multidisciplinary approach. Implications and future research directions to advance sustainability and resilience under a life-cycle perspective are also provided
