Upgrade of the Geissloch Viaduct on the Solothurn-Moutier railway line
2024
A 22-kilometre-long railway line in Switzerland had to be upgraded to meet new regulations, with steel bridge decks replaced by modern steel-concrete composites. The project required a six-week service suspension. VSL Switzerland supplied nearly 400 bridge segment couplers, electrically-insulated prestressing cables and injection grouting, and supervised bridge fabrication, assembly, installation, and grouting on site.
