Slussen

It is known for its locks system between Lake Mälaren and the Baltic Sea, as well as its historic role as a major transport interchange.

[1] Slussen has been a vital crossing point in Stockholm for centuries, linking southern roads with the waterways connecting Lake Mälaren to the Baltic Sea.

Designed by architects Gösta Lundborg and Sven Markelius, the structure was hailed as a modern solution to traffic and pedestrian congestion.

However, the innovative "cloverleaf" design proved problematic as traffic volumes increased, leading to congestion and safety concerns.

The interchange became a symbol of Stockholm's modernity in the mid-20th century, but structural issues began emerging as early as the 1940s due to salt corrosion and other damage.

[4] A central feature of the new design is the Golden Bridge (Guldbron), officially known as Slussbron, which connects Södermalm to Gamla stan.
