Lindapter Hollo-Bolts provided an innovative solution for strengthening the steel bridge decks that were suffering from fatigue cracks.
The Berlin Bridge in Duisburg is one of the longest road bridges in Germany at 1.8km and is part of federal highway 59. It was built between 1960 and 1963 and is a haunched steel girder bridge design with orthotropic steel deck and concrete supporting piers. The deck consists of a structural steel deck plate stiffened with ribs to allow the deck to directly bear vehicular loads and to contribute to the bridge structure's overall load-bearing behaviour.
