Uncontrolled and equivocal uses of well-known structural wood species have influenced shortage of these products on market of structural design. In order to raise awareness of the professionals of building construction about "alternative" wood species, a proposal is here discussed by employing these essences in footbridges. A case study is considered: a hyperestatic trussed arc with intermediate deck, parameters chosen based on local features of structure implementation. This project aims to reduce pressure on traditional species, evidencing "alternative" woods technical capacity, and improve accessibility in crossings over city streets. To provide greater durability to structure life, preservative treatment type has been set. Finally, by results, that it is possible to apply mean strength wood in large structures, requiring only right combination between structural staticity and wood properties.
