A new pedestrian suspension bridge is opening 37 miles southeast of Porto, Portugal, and it’s slated to be the world’s longest at 1,692 feet long. The 516 Arouca is certainly not for the faint of heart as it’s located 576 feet above the Paiva River canyon.

The bridge was constructed using steel cables and an open metal grid. It’s suspended between two V-shaped concrete towers and would take a pedestrian from five to 10 minutes to cross. Maybe a bit longer if you stop to admire the stunning views or if the slight swaying slows you down. It doesn’t have a transparent bottom, so walking across will be slightly less terrifying than crossing the latest glass-bottomed bridges in China (also the longest in the world), but you can still see through the open metal grid flooring.

516 Arouca is now expected to open in 2021 — though an exact date hasn’t been set.
