Kruunuvuori Bridge opening Helsinki marked a rare moment in the city’s transport history on Saturday, as Helsinki opened the long-awaited bridge to pedestrians and cyclists for the first time. Within minutes of the official ceremony, the structure was already filled with people moving slowly across its full length, pausing to look out over the sea and the city skyline.
The opening felt less like a formal infrastructure event and more like a public gathering. Families, cyclists, and visitors arrived early and stayed long after the ribbon was cut, turning the bridge into an immediate part of the city’s daily life, even before tram services begin.
The idea for the Kruunusillat connection is not new. It first entered Helsinki’s planning discussions in 2002. Since then, it has moved through years of design changes, political debate, and cost reviews.
Construction on the bridge itself only began in 2021. Even so, the project reached completion ahead of schedule, a point city officials highlighted during the opening ceremony.
The bridge is the central piece of a larger plan that will eventually connect Laajasalo to central Helsinki by tram.
The opening ceremony was held on both ends of the bridge.
Mayor Daniel Sazonov officially opened the bridge at the Korkeasaari side, while Deputy Mayor Johanna Laisaari led events from Laajasalo. After the ribbon cutting, pedestrians were allowed to cross first, followed later by cyclists.
Crowds formed quickly. Within a short time, the entire 1.2-kilometre span was filled with steady movement. People stopped often, taking photos and watching the water below.
Organisers had encouraged visitors to wear crowns as a playful reference to the name Kruunuvuori. Many did. Some arrived with handmade paper crowns, others with knitted versions or costumes. Music, food stalls, a choir, and a samba group added to the atmosphere, giving the opening the feel of a city festival rather than a transport launch.
The Kruunuvuori Bridge now holds two national records.
It is the longest bridge in Finland at about 1.2 kilometres, and also the highest, with its central pylon rising 135 metres above sea level.
It used 5.8 million kilograms of steel and 22,000 cubic metres of concrete. These figures reflect the scale of construction needed to span the water between Laajasalo and the central islands.
City officials also note that the bridge is unusual internationally. It is designed only for trams, pedestrians, and cyclists. Private cars are not allowed.
The bridge is part of a wider transport shift in eastern Helsinki. Once completed, it will carry a new tram line linking Laajasalo directly to the city centre.
Tram testing has already started. Passenger services are expected to begin in 2027.
The decision to exclude cars was debated for years. Supporters say it prioritises public transport and reduces long-term congestion. Critics argued it limited flexibility. That debate remains part of the bridge’s history, even as it opens to the public.
Mayor Sazonov acknowledged those discussions at the opening, noting that major infrastructure projects often divide opinion before they become part of everyday use.
Because of its height and exposed position over open water, wind has been a key design concern from the start.
The bridge includes structural features intended to reduce wind impact, especially for cyclists and pedestrians. City officials have said it is safe under normal weather conditions, although it may close temporarily during storms or extreme wind events.
The planned lifespan of the structure is 200 years.
The Kruunusillat project, which includes the bridge and tram line, has a total estimated cost of 326 million euros.
Of that, around 155 million euros is linked to bridge construction contracts, 157 million euros to the Laajasalo tram line, and the remainder to additional project costs.
The bridge alone is estimated at about 130 million euros.
For now, the bridge is open only to pedestrians and cyclists. Tram services will follow later, completing the connection between Laajasalo and central Helsinki.
What changes next will not be seen in a single day, but in routine movement. Commuters, cyclists, and tram passengers will gradually replace the opening-day crowds.
Still, the first impression is already clear. The bridge is no longer just a plan or a construction site. It is now part of the city’s physical and social landscape.
