Stadtlau East Railway Bridge, Railway bridge in Donaustadt, Austria

The Stadtlau East Railway Bridge is a railway viaduct in Donaustadt with a steel structure that crosses multiple waterways. The structure connects the Leopoldstadt and Donaustadt districts and carries both passenger and freight trains across its tracks daily.

The original structure dates from 1870 and was replaced in 1931 with a new construction better suited to modern rail traffic. A major elevation of about 4.5 meters took place in 1995 to allow river traffic to pass underneath.

The bridge is named after Stadlau, the Donaustadt district it enters, and it links Leopoldstadt with Donaustadt. Since the Reichsbrücke collapsed in 1976 it has been Vienna's oldest Danube bridge. It is a protected monument, and its 1995 lift of 4.5 metres for the Freudenau power station is visible in the taller piers.

The structure can be viewed from several vantage points along the Danube, particularly from the riverbanks. Keep in mind that this is an active railway viaduct and access to the tracks is not permitted or safe.

The replacement bridge was built beside the old one and slid into place, with work finished in 1932. The original 1870 structure had itself been pushed forward on rollers and pulleys by human power at about four metres per hour, guided by a 31.46-metre curved nose.
