Betcha never seen a bridge like this one: the Slauerhoffbrug (Slauerhoff Bridge) in Leeuwarden, the Netherlands, uses two arms to swing a section of the road in and out of place to let ships through.
The bridge looks like it's flipping pancakes - and one can imagine a hapless car could be catapulted far, far away if it just happens to stop at the wrong section of the bridge!
