Konrad-Adenauer-Brücke, Steel road bridge in Bonn, Germany
The Konrad-Adenauer-Brücke, known locally as the Südbrücke, is a beam bridge of eight spans with a total length of 770 m and a 39.20 m wide deck. Its main river span is a steel box girder 230 m wide, rising from 4.50 m at mid-span to 9.25 m over the piers; the left-bank approach is prestressed concrete. The deck carries the A 562 motorway, tram lines 66 and 68, and foot and cycle paths on both sides.
Architect Gerd Lohmer designed this bridge, which opened in 1972 after five years of construction. It was built as part of the city's modern infrastructure development.
Locals call it the Südbrücke, though it was named after Konrad Adenauer, who died in April 1967 as construction began; the plan to honour Theodor Heuss was dropped. The deck carries tram lines 66 and 68 alongside the A 562 motorway, with foot and cycle paths on both sides. It crosses the Rheinaue park and its Auensee lake.
The bridge carries the A562 motorway and tram lines 66 and 68, with a footpath and cycle path on each side of the 39.2 m wide deck. It crosses the Rhine at kilometre 651.3, passing over the Rheinaue park and its Auensee lake on the left bank. Motorway exits Bonn-Rheinaue and Bonn-Ramersdorf sit at the ends of the main span.
At roughly this spot in Ramersdorf a railway ferry, the Trajekt Bonn–Oberkassel, crossed the Rhine between 1868 and 1919. The bridge's main span of 230 m is carried by a steel box girder whose depth tapers from 9.25 m above the river piers to 4.50 m at mid-span.
