The bridge was built to replace the preexisting trellis bridge.
The new bridge was built by building some concrete piers and installing the main beams, which would have support the reinforced concrete flat arch.
The steel elements were assembled over the right bank of the Breggia river and installed by a specific equipment, exploiting the final supporting piers for the intermediate props.
