Steinitzsteg Footbridge, Pedestrian bridge in Vienna, Austria

Steinitzsteg is an 875 m bridge over the Danube and New Danube in Vienna, linking Brigittenau and Floridsdorf. Downstream of the Nordbrücke, it crosses the Handelskai and Donauuferbahn tracks on a reinforced concrete bridge, then the Danube on a 411 m steel hollow box with trapezoidal cross-section, about 40 m from the Nordbrücke. A further concrete bridge crosses the Danube Island, and a curved steel hollow box spans the New Danube and Hubertusdamm.

The bridge was built in 1995 and briefly carried car traffic during the Nordbrücke renovation in 1996. Since then it has served exclusively as a pedestrian and bicycle route.

The bridge was renamed Steinitzsteg in 2009 after chess world champion Wilhelm Steinitz, who died in Vienna in 1900. On the 110th anniversary of his death in summer 2010, an explanatory plaque was mounted on the bridge. Steinitz was born in Prague in 1836 and became the first official world champion in 1886.

The footbridge is open to foot traffic and cyclists throughout the year and offers a direct crossing between the two districts. The width provides comfortable space for both groups to share the route without congestion.

The bridge was designed so it can be quickly refitted for car traffic; it already carried two lanes during the 1996 Nordbrücke renovation. A further renovation of the Nordbrücke is planned from March 2027 to 2031, when the Steg is to serve again as a diversion route for closed lanes.
