As part of the Provincial Road 66 in “Val d’Ossola”, the bridge over the Meggiana valley was built to by-pass a dangerous hairpin bend of the only road that reaches the Italian side of Monte Rosa.

The structure, built 80 meters above the valley, is made of Corten steel and includes welded joints between the main beams and bolted joints in the internal bracing. In the launching operations for both sides, some supports were installed and kept in place during the subsequent operations by means of DYWIDAG bars, hooked to the abutment. Subsequently, the macro elements were installed as a cantilever, until they were closed by the final element.
