This paper aimed to develop a comparative analysis between bridge superstructures constructed of prefabricated concrete, wood and mixed steel/concrete, for three different spans length. The projects were analyzed for the generation of environmental impact through performance presented in parameters established within the categories: energy consumption, atmospheric emissions and resource depletion. The life cycle analysis of the materials from cradle to gate was carried out. The results allowed to identify the superstructure with the most satisfactory behavior in each parameter. The bridge constructed of wood showed the best results in all of the parameters in the categories atmospheric emissions and resource depletion, on the other hand, presented high energy consumption. In relation to the other superstructures, the best performance in each parameter varies according to the span length. This study is an importanttool to aid decision making with a view to sustainable construction.
