There’s something magical about bridges. They’re often incredible feats of engineering and design. They’re meant to connect people and places that would otherwise have to exist separately. Crossing a bridge is a singular experience. You’re neither here nor there, but hanging in the middle. You could be suspended over a river, hang in a valley, or climb a huge mountain.

Here are 30 of our favorites, found all over the world. Some of them are small, some are huge. Some are pinnacles of cutting-edge engineering technology. Some are ancient, but have stood the test of time. Some are deceptively simple, and some are incredibly intricate.
