This modern day drawbridge is an engineering marvel. Watch how it's odd-looking arm completely removes a section of the road so boats can pass through.

The Slauerhoffbrug (Slauerhoff Bridge) is located in in Leeuwarden, Netherlands. It uses a combination of hydraulics and a 375 metric ton counterweight at the end of the arm to 'fly' a section of the road above the river. Unlike traditional drawbridges which are hinged, the flying bridge completely removes a section of the roadway for boat traffic, then sets it back in place for auto traffic.

See the bridge fly from the perspective of people driving on the road.
