According to La Stampa, hundreds of residents and holidaymakers were present for the bridge's opening ceremony in the town of Tartano in the northern province of Sondrio, which forms part of Italy's border with Switzerland.
The 234 metre-long bridge is suspended 140 metres above the valley floor, making it both the highest and the longest bridge of its kind in Europe.
It connects the hilltop towns of Campo Tartano and Frasnino and provides panoramic views over the Valtellina valley, situated at the foot of the Rhaetian Alps in Lombardy.
Excitement about the bridge has been spreading throughout Italy since a Facebook video of his walk over the structure posted by Luigi Tripiciano went viral on social media.
