What famous overpasses do you know? Why didn't you tell me?

Arizona Grand Canyon Pedestrian Bridge, this transparent-edged pedestrian bridge is located on the western edge of the Grand Canyon. It is outside the Grand Canyon National Park, on the land of the Wallapai tribe. Standing on the edge and looking at the transparent glass floor, you can see the vertical drop of 500 feet (150m) to 800 feet (240m)!
