Reichsbrücke, Multi-level bridge in Leopoldstadt, Austria.

Reichsbrücke is a girder bridge over the Danube in Vienna, connecting Mexikoplatz in Leopoldstadt with Donauinsel in Donaustadt. Its upper deck carries six lanes of road traffic, two footpaths and two cyclepaths, while a lower ramp near the right bank descends beneath the main deck. The bridge also carries U-Bahn tracks and two utility tunnels.

The first crossing at this location opened in 1876 as Crown Prince Rudolf Bridge, serving the growing city as a major link across the river. After the collapse of the previous structure in 1976, the current version was built by 1980.

The name refers to the historical monarchy and remains part of everyday conversation among locals crossing the Danube. Many residents from surrounding districts use the wide walkways as a daily route between home and work, making the span a natural part of neighborhood life.

Cycling paths and pedestrian walkways run on both sides of the roadway, allowing safe crossing for walkers and riders throughout the day. The Donauinsel metro station sits directly at the span and offers quick access to the island and neighboring districts.

The bridge carries six traffic lanes, U-Bahn tracks, two footpaths, two cyclepaths and two utility tunnels, used by about 50,000 vehicles a day. Its 1978–1980 construction followed a design competition won by a project named after playwright Johann Nestroy; the official name Johann-Nestroy-Brücke never caught on. The U-Bahn first ran across it on 3 September 1982.
