Each triangular element rests on the one before and the one after. It’s placed on wooden beams that transfer the loads to the structure. The bridge deck is created by the space between them. In order to build the bridge, we optimized it by having two connected reciprocal structures (making the bridge more stable and blocking the horizontal movement). The purpose of the first bridge was to create two arches composed of isosceles triangles and to mirror them to make the bridge more stable. During the first week, experiments around the triangle and the Leonardo da Vinci bridge were made, with different shapes, sizes, thicknesses, and different assemblies such as notches, nails, joints, etc.
