Sluppenbrua (lit. Sluppen Bridge) is a road bridge across the Nidelva river in Trondheim, Norway. It is 82 meters long, and is currently a pedestrian and cycling bridge.

Originally, Sluppenbrua was built as a railway bridge on the Trondhjem–Støren Line, which was opened in 1864. This bridge was around 200 m long og 30 m tall, made by timber standing on a foundations of rock. This bridge was torn down in 1884 when the new Dovre Line going by Nidareid was opened. The foundations were transferred for free to the Norwegian Public Roads Administration in 1927 with the intent to build a road bridge on the same spot.

The new road bridge was postponed, resulting in the first road bridge to be built being a provisional truss bridge built in wood by order of the German military. This bridge was opened in July 1942. The wood was not waterproofed, which meant that the bridge gradually decayed and had to be closed.^[when?] A new bridge made of steel was opened in 1954. In 1977 the bridge was equipped with a separate path for pedestrians and cyclists. Today the bridge still stands on the same foundations from 1864.

Until October 2023 the bridge was a part of Norwegian National Road 706 (riksvei 706) before the adjacent Nydalsbrua was finished, and is now solely used by cyclists and pedestrians.
