Flehe Bridge, Cable-stayed road bridge in Neuss, Germany

The Flehe Bridge is a single-tower cable-stayed bridge carrying the A46 motorway over the Rhine between Düsseldorf and Neuss. Its 146.47-metre reinforced concrete pylon stands on the left bank and splits into two legs like an inverted Y; the legs are only 6.4 metres wide along the bridge axis and hold a lift and stairs above the roadway. The main span over the river is 368 metres, with a 41.7-metre-wide steel box-girder deck, and the 780-metre prestressed concrete approach viaduct has 13 spans of 60 metres. The bridge crosses the river at a skew to spare the Flehe waterworks intake area.

The bridge was built from 1976 and opened on 3 November 1979, costing 94.6 million DM. Its overall concept came from Gerd Lohmer, while Fritz Leonhardt planned the foreland bridge on the Neuss side. At completion its 368 m main span made it the world's longest single-pylon cable-stayed span. It relieved Düsseldorf's South Bridge and linked the A 46 with the A 57.

The bridge takes its name from Flehe, the Düsseldorf district on the right bank. Its opening on 3 November 1979 drew through traffic out of southern Düsseldorf and ended the South Bridge's role as the only southern Rhine crossing into the city. Residents later pressed for noise protection through the Fleher Bürger-Interessengemeinschaft, and a 1.50 m wall followed by the end of 2012.

The bridge carries motorway traffic and has dedicated pedestrian and bicycle paths on both sides for safe crossings. Visitors can best view the structure from the riverbanks or nearby viewpoints to appreciate its full scale.

The pylon is a reinforced-concrete mast 146.47 metres tall, shaped like an upside-down Y, with its two legs only 6.4 metres wide along the bridge axis. An elevator and a staircase are housed inside the legs above the roadway, built with climbing formwork. Until the first new A40 Rhine bridge in Duisburg opened in 2023, it was Germany's tallest bridge pylon.
