The exposed location above the town, a large number of intersecting traffic routes, the Sieg river, a rail line, and an overhead power line are among some of the factors which make the Siegtal replacement bridge project an extremely challenging design and planning task.
The design team, comprising Dissing+Weitling, Schlaich Bergermann Partner, WTM Engineers and Marx Krontal Partner, deal with the challenges concerning the height of the bridge as well as how to cause as minimal discomfort as possible for the users and neighbors of the bridge.
For the competition phase Dissing+Weitling created three, potential designs characterised by different types of pillars.
The preferred type is a cable-stayed bridge with spans of up to 192 metres. Alongside structural engineering aspects, economic, design, and sustainability aspects are investigated.
