For almost 120 years, the Letten Viaduct has led northwards across a former industrial area not far from Zurich Hauptbahnhof (main station). The numerous natural stone arches of the structure have always been used as storage areas, mostly in an improvised spontaneous fashion, but also for shops and restaurants. The growing pressure of the city has made these residual areas for creative use increasingly more attractive.

By 2010 and under the label "In the Viaduct", new uniformly designed spaces for shops, cafés and general services were created in the 53 arches of the bridge, which even with limited building costs met the increased requirements for energy efficiency, hygiene and fire safety. At the junction with the Wipkinger Viaduct emerged in addition Zurich's first covered market hall.
