Seitenhafenbrücke, Road bridge over the Danube Canal in Vienna, Austria

The Seitenhafenbrücke is a road bridge opened in 2011 that spans the Danube Canal, linking Seitenhafenstraße on the left bank in Vienna's 2nd district with 11. Haidequerstraße on the right bank in the 11th district. It is the newest road bridge over the canal and stands beside the Freudenau harbour, known locally as the Winterhafen.

The Seitenhafenbrücke opened in autumn 2011, making it the newest road bridge over the Danube Canal in Vienna. It was built to relieve the Freudenauer Hafenbrücke, about 1.2 km downstream, and to shift traffic from the Handelskai to the Simmeringer Haide junction of the A4 motorway away from the residential areas of Kaiserebersdorf. Before the bridge, no crossing stood at this site.

The bridge's name comes from the Seitenhafen, a harbour basin that once ran alongside the Seitenhafenstraße until it was filled in around 1980. Until the bridge opened, that street was a dead end at the Danube Canal. The crossing now links the 2nd district with the 11th, where the 11. Haidequerstraße leads to the Pfaffenau waste incineration plant and Vienna's main sewage treatment works.

The bridge provides safe crossings for all types of traffic with dedicated pathways and roadways. When visiting the surrounding neighborhoods, it is easy to reach on foot or by bicycle.
