Südbahnhofbrücke, Urban transportation bridge at Arsenal district, Vienna, Austria.

The Südbahnhofbrücke carries road traffic, pedestrians and cyclists over the Hauptbahnhof tracks on two steel decks, each 60 metres long and more than 17 metres wide, resting on Y-shaped piers. Its flat arch girders are tilted toward each other, a lean repeated in the railings and abutment faces. It continues Franz-Grill-Strasse from the 3rd district and crosses Arsenalstrasse and the tracks.

Construction started in 2010 following a design by Albert Wimmer, but opening was delayed until August 2018 due to technical requirements. The bridge was built as part of the area's transformation after the old station was demolished.

The bridge is named after the Südbahnhof, which was demolished in 2009/2010; the Hauptbahnhof was built on its site by 2015. From 1956 the Südbahn and Ostbahn shared a station of two terminal halls with one handling building, and because the Südbahn was the more important line after 1945, the whole station took its name.

The bridge provides separate lanes for vehicles, cyclists, and pedestrians with good accessibility for all users. A spiral ramp from Arsenalstrasse offers stairs-free access for those on foot or bicycle.

The 460-tonne steel deck was lifted into place on 5 October 2010 and then rotated sideways by 45 degrees on a temporary track. The two flat arch girders lean toward each other, a tilt repeated in the railings and abutment faces.
