If this bridge in Oberhausen, Germany, reminds you of a slinky toy, that’s exactly what inspired it. German artist Tobias Rehberger spiraled 496 coils around a rainbow colored walkway that crosses over a canal to connect two existing parks. Rehberger collaborated with structural engineers Schlaich Bergermann and Partner to realize his design. The structure consists of pre-cast concrete plates, spiral bars and railing made of steel and net cable, all attached to high-strength steel stress ribbons connected to the inclined supports on both sides of the canal. The 1,332 foot walkway has a synthetic finish that kind of bounces when you walk. It is presented in 16 different colors, matched in color on the underside of the bridge which is made out of a different material. The Slinky Bridge is luminous with color and definitely puts a spring in your walk.
