The Slauerhoffbrug (English: Slauerhoff Bridge) is a fully automatic bascule bridge (aka tail bridge)^[1] in the city of Leeuwarden in the Netherlands. It is a road bridge that carries the Slauerhoffweg (named after J. Slauerhoff) over the Harlingervaart. It was completed in 2000.

The bridge uses two arms to swing a 15×15m section of road in and out of place.^[2] The lift arms are oriented diagonally to the road. The bridge is painted in yellow and blue, representative of Leeuwarden's flag and seal.^[1] This movable bridge is also known as the “Slauerhoffbrug ‘Flying’ Drawbridge” or Frog Bridge (Dutch: Kikkerbrug), the last because of its shape in the down position. One of the main designers is Emile Asari. A tail bridge can quickly and efficiently be raised and lowered from one pylon (instead of hinges). This allows water traffic to pass while only briefly blocking road traffic.^[1]
