Siegtalbrücke, Highway bridge in Siegen, Germany
The Siegtal Bridge is a road bridge over the Sieg Valley in Siegen that rises 106 meters high and stretches roughly 1,050 meters across. It features a prestressed concrete hollow-box design that carries vehicles on two separate decks across twelve spans.
Construction took place between 1964 and 1969 as part of the A45 motorway expansion, marking an important infrastructure project during post-war Germany's rebuild. The bridge's completion improved transportation connections between regions and has shaped the landscape ever since.
The bridge stands as a recognizable landmark that locals navigate by, visible from many parts of the city. It shows how modern construction shapes the landscape and connects different neighborhoods together.
The bridge carries heavy daily traffic, so expect delays during rush hours if you're driving across it. Best viewing opportunities come from surrounding vantage points around the valley that let you see its full height and scale.
A 110-kilovolt power line runs beneath the bridge, revealing the complex infrastructure needed to operate such large structures. This technical connection shows how modern bridges function not in isolation but as part of a larger network.
