Aspernbrücke, Steel girder road bridge in Vienna, Austria

Aspernbrücke is a steel bridge over the Danube Canal linking Vienna's Innere Stadt with Leopoldstadt, about 800 metres northeast of Stephansdom. The current structure, built 1949–1951 to plans by Erich Franz Leischner, is 88.97 metres long, 27.95 metres wide and weighs 925 tonnes. It stands next to the Urania and near where the Wienfluss meets the canal.

Construction started in 1949 as part of Vienna's post-war reconstruction efforts, with the bridge opening in 1951. It was designed to restore vital infrastructure connections in the damaged city.

The bridge is named after the 1809 Battle of Aspern, where Archduke Karl defeated Napoleon; it was given this name on 14 July 1864. The first bridge, opened by Emperor Franz Joseph I on 30 November 1864, carried allegorical figures by Franz Melnitzky representing war, peace, fame and prosperity, with stone lions placed in front of them. Two of those lions now stand at the entrance to Horn Castle, the other two at Schloss Gobelsburg in the Kamptal.

The bridge experiences peak traffic during daytime hours when cars, trams, and cyclists all share the space together. The pedestrian section is clearly marked and remains safe to cross even when vehicle traffic is heavy.

The first Aspernbrücke, a chain bridge opened in 1864, carried four allegorical figures by Franz Melnitzky on its anchor pedestals, symbolising war, peace, fame and prosperity, with stone lions placed in front of them. Two of these lions now stand at the entrance to Horn Castle, the other two at the drive of Gobelsburg Castle in the Kamptal.
