The 4th bridge across the Danube river in Linz is part of a major infrastructure project that 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, making the 4-lane highway bridge a true 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 twelve fully locked and heavy galvanized spiral cables. The cable clamps are cast elements.
Thanks to the unique circumstances of the site, the result is a very slender and transparent design, perfectly adapted to the highly sensitive ecology of the area and the beautiful landscape of the Danube valley.
