The "Deutsches Museum München" is the largest science museum in Germany. This bridge is a part of the exposition on Bridge and Water Engineering. It's not a usual bridge that spans over an obstacle but it was designed to be a full scale exhibit that demonstrates the state of the art in bridge engineering and to make the structure comprehensible for laymen as well as interesting for the professional. Four different structural systems were combinded to make up the bridge: the circular ring beam supported only on the inside, the suspension bridge that forms the supports of the ring beam, the frame girder to stiffen the ring beam for uniform loads, and the deck made of glass. For transparence all these structural elements were reduced to their mimimum.
