This viral video gives you a front-seat view of what it looks like to drive over a floating pontoon bridge that spans the Nadym River in Russia. To put it simply, it looks terrifying. The footage of cars driving slowly across the half-submerged bridge is already pretty harrowing (the music doesn't make it any less tense) — and that's before a huge, heavy truck cuts up the outside lane, weighing the bridge down and causing water to bubble up around the cars. Watch from 1:20 to see what happens.
