Sihlhochstrasse

Sihlhochstrasse is a road bridge spanning the Sihl River in Zürich, connecting the Brunau and Wiedikon districts. It carries six lanes of traffic and serves as a major thoroughfare in the city's transportation network.

Built between 1969 and 1973, the bridge was part of an ambitious plan to reshape the city's highway network. Construction methods like prestressed concrete reflected the engineering approaches of that period.

The concrete structure represents Swiss engineering precision with its hollow box design and systematic placement of support piers every 42.4 meters.

The bridge is accessible 24 hours a day and can be crossed on foot or by car. Traffic congestion may occur during peak hours, so plan your crossing accordingly.

The bridge ends abruptly at a retaining wall because the planned highway extension was never completed. This unfinished ending is a visible reminder of transportation planning decisions from the 1970s.
