Plauer Brücke, Road bridge across Havel River in Brandenburg an der Havel, Germany

Plauer Brücke is a riveted steel truss bridge with half-parabolic trusses crossing the Havel between Plaue and Margarethenhof. It is 130 metres long and 10.7 metres wide, with two piers in the riverbed and a 42.7-metre span between them. The roadway is paved, and the railings are designed in Jugendstil forms.

A bridge existed at this narrow point of the Havel as early as the 13th century; it was destroyed in 1244 and rebuilt from 1459, then repeatedly wrecked in wars including the Thirty Years' War. The newly built bridge collapsed under load in 1829 on the Berlin–Magdeburg post route, and the crossing was rebuilt between 1836 and 1837. The present riveted steel truss bridge dates from 1903–1904; its central section was destroyed at the end of World War II and later rebuilt. After full closure since October 2020, it reopened on 30 March 2026 following a roughly five-million-euro restoration.

The bridge's name distinguishes it from the newer Havel crossing opened in 2002, after which it is called Alte Plauer Brücke. Its riveted half-parabola trusses and Jugendstil railings survive from the 1903–1904 build, and the historic railings are being restored and reattached piece by piece.

The bridge now serves only pedestrians and cyclists, while vehicle traffic uses the adjacent newer structure. Walking or cycling across offers good views of the river and surroundings from the deck.

The bridge is one of the few surviving pre-World War I bridges in the region, and its Art Nouveau railings are being restored and reattached piece by piece after the 2020–2026 renovation. The old wooden footways remain closed, so the restored railings are best seen from the deck.
