The world’s longest pedestrian suspension bridge has recently opened in Portugal.
Stretching 516 metres, the 516 Arouca Bridge surpasses the 494m-long Charles Kuonen bridge in the Swiss Alps to become the world’s longest pedestrian bridge of its kind.
It was designed by Itecons, an institute for construction, energy and the environment at the University of Coimbra, and constructed by Portuguese contractor Conduril. It cost €2.3m (£2m) and took three years to build.
The structure is made of steel, supported by two V-shaped concrete towers. The designers chose to use a metal grid for the floor and side railings, to give unobstructed views of the verdant mountains and the rocky gorge.
The new bridge is part of an initiative set out by the Portuguese government to drive more tourists to the area. It connects into a 9km series of wooden walkways along the left bank of the Paiva River, where travellers can explore river beaches and quartz formations, besides viewing wildlife unique to Portugal.
