In Riedlingen, extensive flood protection measures were necessary, in the context of which three new bridges were built.
First of all, the road bridge over the flood channel was commissioned, as an existing truss girder structure from 1901 had to be replaced in the course of flood protection measures. In order to suit the setting as a modern gateway to the listed old town, a competition was held in 2003. The design of an integral steel composite bridge convinced the jury. As a characteristic element, the supporting structure lies above the carriageway. The bridge is characterised by two elegant, flat, curved arches, which are arranged in the bridge cross-section between the carriageway and the footpath and cycle path, thus safely separating the different traffic areas from each other. The monolithic connection of the individual components enables a slender, robust and low-maintenance construction, manufactured in a very short construction time.
60 m up the canal an unobtrusive truss structure, the Inselbrücke, connects the local recreation area "Donauinsel" with the pedestrian zone in the old town for pedestrians and cyclists. The distribution of the falling diagonals, optimized according to the flow of forces, rhythmizes the view.
At the northern edge of the old town of Riedlingen, a graceful footbridge, the Stadtgrabensteg, leads over the former moat. The delicate steel arched bridge is characterised by filigree stakets that form the railing in the extension - a constructive counterpart to the large road bridge over the flood channel.
