Foot and cycle path bridge crosses the Siegburg city wall

Holz-Beton-Verbundbrücke im historischen Kontext, Siegburg

Description

The district town of Siegburg intends to relieve Kaiserstraße of the currently crossing through traffic by means of a new traffic junction between Burggasse and Ringstraße. This measure is to be realised in the form of a footbridge connecting the two streets across a ditch. The area below the footbridge is to be converted into a green space with an attractive quality of stay and at the same time the crossing city wall and the adjacent moat are to be made more tangible. The resulting pathway between Burggasse and Ringstraße in direct connection to Kaiserstraße will invite visitors to walk through and also to linger and experience the historical area.

The planned footbridge will be carefully integrated into the urban environment and the surrounding green space. The abutment on the Burggasse side will be placed so that it lies behind the historic city wall, which currently runs in the ground, causing the footbridge to run over the city wall. The footbridge is planned with two intermediate piers and will have a curved S-shaped course in plan. Due to a height difference of about 1.5 metres between the connection at Burggasse and Ringstraße, a gentle ramp is planned that leads from Ringstraße to the beginning of the bridge.

The planning group’s aspiration was to consider sustainability aspects already in the planning stage, which influenced the main approach in the choice of the supporting structure for the footbridge. The planning group’s aspiration was to take sustainability aspects into account as early as the planning stage, which influenced the main approach in the choice of the supporting structure for the footbridge. The timber-concrete composite superstructure means that sustainable building materials are used where they can show their great advantages: the use of reinforced concrete can be significantly reduced in this structure due to the composite construction method, and the formation of the caps on the web flanks from European natural stone also means that a very durable and sustainable material is used.
