The 300ft-long (about 91 meters) pedestrian bridge has been constructed at 9,977 ft (about 3 000 meters) above the sea level on Mount Titlis.
It is deemed to mark the centenary of a cableway that connects two nearby towns, Engelberg and Gerschnialp.
The cableway began operating in January 1913.
Entrance to the bridge, which is only 3ft in width (about 1 meter) will be free.
The bridge is built of concrete and steel.
“Europe's highest suspension bridge will allow us to bring guests a step closer to the Alps and let them experience the height, vastness and majesty of the mountains from the most impressive of platforms," the local tourism authority said on its website.
