Pedestrian Bridge at the Mozart Tower, Darmstadt, 2005
The Mozart Bridge connects the Darmstadt Europa Viertel (Europe Quarter) and the Rhine-Main Technology Center to create the largest technology center in Hessen. The train station will also be connected to this center however, without negative affects on historic Rhein Street. From a motorist's view direction, the bridge appears as snippets of silver ribbon that seemingly hang from the treetops over a strip of Rhein Street. From pedestrian's view point, the bridge is a composition of complex leveled plains, folded in one another, which define the support structure of the bridge and its ramps. The bridge's delicate construction, with its glass railings and 40 centimeter thick panels, allow for an unobstructed view along the centerline of the historical city, including the castle and the Ludwigssäule (Ludwig's Pillar). The continuing bridge strip of around 200 meters long is uniquely designed to act as a large clamp which connects city quarters. At its widest point the bridge has a width of approximately 60 meters, and where pedestrians and cyclists pass each other it has a clear minimum width of 4 meters. The bridge's opening ramps have middle platforms, which have a depth of 1.5 meters, and are arranged every 10 meters. Through plan-differed arrangement, the static basic-module (consisting of spatially effective, non-altering half-frames) becomes connected through a comprehensive support structure of three-hinged frames. A hybrid frame exists consisting of roadway plates and dynamic pairs of half-frames which are dependent off one another and build balance only by working together. The bridge construction is materialized in reinforced concrete and steel.
