Measuring 1,692-feet long, Arouca 516 in Portugal is now the world’s longest pedestrian suspension bridge. It sits 574-feet above the Paiva River and is now open to the public, built at a cost of around $2.8-million USD. The structure itself is supported by two V-shaped concrete towers, and will takes approximately 10 minutes to cross. To keep guests safe, the floor and side railings are made of rugged metal grids, which also provide expansive views of mountains and river gorge.
