The construction industry is increasingly recognized as critical in achieving Sustainable Development Goals. Construction activities and infrastructure have both beneficial and non-beneficial impacts, making infrastructure design a focal point of current research investigating how best to contribute to sustainability as society demands. Although methods exist to assess infrastructures' economic, environmental, and social life cycle, the challenge remains in combining these dimensions into a single holistic indicator to facilitate decision-making. This study applies four decision-making techniques (ANP, TOPSIS, COPRAS, and VIKOR) to evaluate five different design alternatives for a concrete bridge exposed to a coastal environment. The results indicate that concretes containing even small amounts of silica fume perform better over their life cycle than other solutions usually considered to increase durability, such as water/cement ratio reduction or concrete cover increase
