A decisive factor in the design for this curvy bridge for pedestrians and cyclists was the preservation of as many of the old trees as possible. This is why the bridge elegantly winds its way over Rheinstrasse and playfully serpentines its long ramps among the trees. In order to shorten the handicapped-accessible pathway along the ramps and bridge, stairways have been added on both sides. People with limited mobility, as well as cyclists, can conveniently cross Rheinstrasse on the long, spiral ramps.
The design of the bridge, which is 350 m long and 3 m wide, develops from a trough construction that lies on V-shaped double supports. The outside of the trough is characterized by U-shaped ribs and is a restrained steel-grey. The various effects of light and shade of the exterior constructive sheeting change the view of the bridge throughout the day and accentuate the dynamic course of the curvilinear pathway.
From every perspective, the geometric course of the winding structure reveals views of the gleaming red interior of the trough. This red accompanies those crossing the bridge on their way from the main railway station to the Technology Centre. LED lighting has been integrated into the handrails. In the evenings the entire length of the bridge is illuminated, and the red colour on the inside takes on a soft glow.
