The 4th bridge across the Danube river in Linz is part of the major infrastructure project A26 bypass West and crosses one of the busiest waterways in Europe as well as railway tracks and a road.
The precipices of the Danube valley allow a direct anchorage of the main cables, without pylons, so that the 4-lane highway bridge will be a real suspension bridge. The superstructure is designed as a steel compound construction with one central steel box girder and steel cross beams. Each of the main cable bundles is made of 12 fully locked and heavy galvanized spiral cables. The cable clamps are cast elements.
Thanks to the unique circumstances, the result is a very slender and transparent construction, perfectly adapting into the ecologically highly sensitive planning area and to the beautiful landscape of the Danube valley.
