History
:
Slussen has been a vital crossing point in Stockholm for centuries, linking southern roads with the waterways connecting Lake Mälaren to the Baltic Sea. Over time, the area has undergone significant transformations.
Early History
The first lock at Slussen, known as Queen Christina's Lock, was inaugurated in 1642. It was replaced in 1755 by Christopher Polhem's Lock. Nils Ericson's Lock, built in 1850, followed, allowing ships to traverse the area more efficiently. The final major lock, Karl Johan's Lock, was inaugurated in 1935 as part of the modernisation of the area.
1935 Traffic Interchange
The 1935 traffic interchange was a pioneering example of functionalist urban planning. 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.
Redevelopment 2016–2027

:
In the early 2000s, the deteriorating state of the 1935 interchange prompted the decision to rebuild the area entirely. A design competition in 2007 led to plans by
Foster + Partners and Berg Arkitektkontor being approved in 2011. Construction began in 2016, with completion scheduled for 2027. The project is to rebuild water regulation infrastructure, while modernising Slussen as a mixed-use public space with improvised public transport.
Cultural and Political Impact
The redevelopment project has faced criticism and public debate. Some have opposed the loss of the historic 1935 structure, while others support the need for modernisation. The new design includes parks, plazas, and waterfront promenades, aiming to revitalise the area.
Golden Bridge and Traffic Layout

A central feature of the new design is the ''Golden Bridge'' (''Guldbron''), officially known as Slussbron, which connects

and shipped to Stockholm in 2020, where it opened to traffic on 26 October 2020.
Public Transport
Slussen metro station lies in the southwest, under Ryssgården.
The Slussen bus terminal temporarily moved eastward to
Stadsgården during redevelopment. By August 2024, buses were relocated to a temporary terminal at Stadsgårdsterminalen. A permanent terminal is under construction inside the bedrock at Katarinaberget.
The
Saltsjöbanan railway terminus is closed during the works, with Henriksdal station serving as the interim terminus.
The
Djurgården ferry has moved its departure point further north but retains the name ''Slussen''.
Waterways
The new water facilities include two discharge channels and the newly named ''
Victoria Slussen''.
These are surrounded by four low bridges and form the heart of Vattentorget, which opened in phases in 2022 and 2024. The original Nils Ericson lock has been repurposed into a fish migration channel as of 2024.
