The Lavant Viaduct, situated in 'Twimberg', 'Austria', became a crucial element of a significant bridge project. The project featured the implementation of sliding finger joints developed by the engineering firm mageba, capable of accommodating movements up to 500 mm and 600 mm respectively. These sophisticated components played a fundamental role in ensuring the structural integrity and longevity of the bridge.

Noteworthy for their innovative design, these sliding finger joints introduced a new paradigm to road crossings. Utilizing a metal-elastomer fusion system, they imparted "internal" flexibility to the bridge, enabling them to adapt seamlessly to dynamic conditions. During installation, a pre-stressing mechanism was employed, ensuring a consistent and gentle pressure on the sliding surface. This innovative feature facilitated the absorption of vertical bridge movements, significantly enhancing overall structural robustness.

The installation of mageba's advanced sliding finger joints coincided with the finalization of the bridge project in 2007, marking a pivotal juncture in the development of the infrastructure. The bridge itself, a remarkable example of a box girder construction, spans an impressive 1,079 meters. Its construction, initiated in 2004, represented a collaborative endeavor aimed at fortifying local infrastructure and fostering enhanced connectivity.

The selection of mageba's sliding finger joints underscores the company's dedication to addressing the evolving challenges of contemporary bridge construction. By introducing innovative solutions, mageba continues to contribute to the resilience and sustainability of vital road networks.
