Portugal opens world's longest pedestrian suspension bridge

• Children younger than 6 are not allowed on the bridge. All visits must be with a guide.
• The project has been under construction since May 2018 and "is inspired by the Inca bridges that spanned the Andes mountain valleys," according to a release.
• "The hanging bridge is supported by two V-shaped concrete towers, and reportedly takes about 10 minutes to cross. Its floor and side railings are made of metal grids, providing a largely unobstructed view of the lush mountains and river gorge," NPR writes.

The bridge opened to local Arouca residents on Thursday, per NPR.

What they're saying: "I was a little afraid, but it was so worth it," Hugo Xavier, the first member of the public to cross the bridge, said, per the Guardian.

The bottom line: "If you don't suffer from the heart, this adventure is for you!" the bridge's website says.
