The Ostbahnbrücke is located near the power station in Simmering and the Gasometer.
The Ostbahnbrücke was designed by Anton Battig and August Friedrich Nathanael Köstlin.
It was constructed in 1870 by the German company C. Harkort and is a truss bridge supporting two sets of rails.
In 1939, the Ostbahnbrücke was strengthened by the Nazis, in order to withhold the increased strain being placed on the bridge by heavier freight transports.
The imminent war was probably also a motivation for this work, as it would require greater levels of freight transport.
