The bridge design created by Riegler Riewe Architects and schlaich bergermann partner as part of the competition for the Tegetthoff bridge in Graz, Austria, has been awarded with a commendation. The 64 m long road bridge, which also features a tramline, crosses the river Mur. For the replacement of the inner-city bridge, a total of 21 interdisciplinary teams had submitted proposals.
The static principle of the design is the so-called “Langer’s girder”—a bridge with self-anchored arches and a suspended deck beam. The arch reaches up to 23 m in height.
The jury praised the economical, minimal heights of the deck girders and the extremely slim cross-section of the supporting arches.
