New Kruunuvuorensilta Bridge, connecting Korkeasaari and Kruunuvuorenranta, is the longest and tallest bridge in Finland. It is also exceptional on a global scale, as bridges of this size are rarely built exclusively for public transport, pedestrians and cyclists. In addition to its scale, the bridge stands out as an attraction due to advanced traffic planning embedded in its design, while its high-quality architectural expression establishes a distinctive new identity for Helsinki’s skyline. The bridge opened to the public in April 2026 and attracted more than 50,000 visitors during opening weekend.

Kruunuvuorensilta Bridge is exceptional even globally, as bridges of this size are rarely designed solely for public transport, pedestrians and cyclists, excluding all car traffic. The bridge is part of Crown Bridges Light Rail project, one of Helsinki’s largest urban development initiatives, which includes three bridges and a new tramline connecting the city center to Laajasalo island. The population of Laajasalo is expected to double by 2040, and the new connection will ensure smooth and reliable public transport for the growing area.

The central structural component and most visible feature of the bridge is its 442-foot-high diamond shaped pylon. It is taller than Finland’s highest residential building, Kalasatama tower, and significantly higher than Olympic Stadium tower. The construction of the pylon alone took approximately two years of continuous concrete casting.

“Kruunuvuorensilta bridge is the new, unique and exciting landmark for Helsinki. A sight that will draw visitors from near and far. The new bridge reshapes how we look at Helsinki. It attaches the areas of Kruunuvuorenranta and Laajasalo in a completely new way to the larger central city area. The bridge reflects our commitment to sustainable solutions and embraces Helsinki’s unique maritime setting,” said Mayor Daniel Sazonov.

The bridge and upcoming tramline reflect Helsinki’s long-term vision of prioritizing public transport, walking and cycling in urban mobility. Already today, the majority of journeys in Helsinki are made using sustainable modes: around 41 percent on foot, 25 percent by public transport and 11 percent by bike, while only about 20 percent are made by car.

New districts such as Kruunuvuorenranta and Kalasatama have been planned around this principle, with the new connection enabling smooth, car-light mobility between them and the city center. The tramway was selected as the primary mode of transport as it provides a fast and reliable connection, supports urban growth, and reduces pressure on existing metro capacity.

Kruunuvuorensilta has a design life of up to 200 years. Together with its dedicated use for tram and active mobility, the bridge reflects Helsinki’s commitment to sustainable long-term urban mobility.

The project has included a comprehensive assessment of environmental impacts, covering waterways, fish populations and boating, as well as noise and vibration. Emissions have been reduced through the use of low-emission materials and renewable energy sources.

Helsinki’s coastal location brings a wide range of weather conditions, from bright summer days to windy and icy winters, placing diverse demands on infrastructure. The bridge’s stay cables are designed to remain in constant slight motion in the wind, to prevent ice formation. Ice accumulation is further reduced by enclosing cables in textured plastic sheaths that cause ice to break off into fine particles. The bridge will also feature a wind warning system, with strong wind alerts displayed on light boards at both ends.
