The Slinky Springs Bridge /Oberhausen, Germany / SBP,Studio
The elegant pedestrian bridge across the Rhine-Herne canal is a part of the project “EMSCHERKUNST 2010”. Following the design of the artist Tobias Rehberger, a colorful ribbon wrapped in a light, swinging spiral connects the two existing parks. The lightness of this design is due to the minimalist structural design of the stress ribbon bridge. Two steel ribbons made of high strength steel connect to the inclined supports across the canal. The resulting tension force is transferred into strong abutments through the outer vertical tension rods. The walkway consists of pre-cast concrete plates, bolted to the stress ribbon, to which the railing and spiral are attached. The springy synthetic pavement of the walkway as well as the colorful rhythmization of the concrete and coating amplifies the dynamic experience of the bridge. Railings made of steel and cable nets effectively add to the dampening of this animated bridge.
