Hardturmviadukt

The Hardturmviadukt is a railway bridge in Zurich approximately 1,100 meters long and crosses railway tracks, industrial areas, streets and the Limmat River. The structure is made of prestressed concrete and features a Y-shaped layout with both single and double-track sections.

The viaduct opened in 1969 as Switzerland's longest railway bridge at that time and was the first structure worldwide to use concrete hinges in its design. The bridge lost its length record in 2015 but remained a significant example of post-war infrastructure.

The bridge is a landmark of Zurich's industrial zone and has shaped the area's identity since its opening. It connects neighborhoods that would otherwise be difficult to cross and enables daily movement for thousands of commuters.

The bridge is accessible from several train stations and located in a well-connected industrial area. Visitors can view the structure from ground level or from various viewing points nearby.

Since 2005 the bridge has been illuminated at night and is part of an urban lighting project. This lighting system transforms the concrete structure after dark and makes it a visual feature of the nightscape.
