Aussersihler Viadukt, Railway bridge in Zürich-West, Switzerland.
The Aussersihler Viadukt is a stone railway bridge in the Zürich-West district, built with 36 arches that run in a continuous line across the area. It carries an active rail line over the neighborhood and is listed as a class B Swiss cultural property of regional significance.
Work on the viaduct started in 1875 and was finished in 1894, when the rail connection it carries was put into service. It was built during a period of rapid expansion in Zürich, when the western districts were being developed for industry and transport.
The arches beneath the viaduct house a street market where local vendors sell fresh produce and regional goods. Walking through it gives a clear sense of how the neighborhood uses the space day to day.
The viaduct is easy to reach on foot from the city center and sits in a part of Zürich-West with many other places nearby. The best time to see the arches from below is during the day, when the market area under them is open and accessible.
Despite being damaged during the Second World War, the viaduct never went out of service and still carries trains today. That kind of continuity over more than a century of use is uncommon for a structure of this age.
