If you have a fear of heights, please take your medication before watching. We will introduce you to the 20 most dangerous bridge tops in the world that will make your hands and feet tremble.

Back before online classes were all the rage, kids had all sorts of ways to get to school. Some hopped on public transport, others hoofed it on foot. And in certain spots, geography meant slingin’ across a dang ol’ suspension bridge was the way to go.

Indonesia’s got a bunch of these suspension bridges, but the Mystery Bridge? That thing lives up to its name. Started out lookin’ safe enough, but a few years down the line, one side’s just hangin’ there, lookin’ like it’s about to give way any second. Even still, local kids are brave enough to cross that rickety thing to get to school. Talk about dedication!
