Merihaka bridge, Helsinki

The bridge is a new bridge that connects Merihaka to the southern part of Kalasatama, Nihti. At its western end, the bridge joins Hakaniemenranta and in the east, it meets Nihti Konttisatamankatu and Sompasaarenkatu intersection.
Construction started in the autumn of 2022. The Sea Shark Bridge was opened to pedestrians and cyclists in June 2025.

There is also a reservation for the future Coal Harbour Bridge, which will lead to Hanasaari. Although no decision has yet been made on its construction, the Sea Hawaii Bridge has been designed in such a way that it will be possible to carry out the connection at a later date.

The Merihaka bridge is connected from its western end to Hakaniemenranta and from its eastern end to the Nihti Konttisatamankatu and Sompasaarenkatu junction.

The Merihaka bridge – a new connection in the heart of the city

The sea shark bridge is part of the Crown Bridges tramway and serves not only trams, but also pedestrians and cyclists. The bridge is closed to motor vehicles, except for rescue vehicles.
The bridge is 422 meters long. The tramway runs in the middle of it and has sidewalks on both sides. The width at the northern edge is 2.5 meters, at the southern side 2.5-3.5 meters. A 4-meter-wide cycle path runs along the southern edge. The structure of the bridge is a reinforced concrete continuous slab bridge and the lighting is implemented with luminaires that can be hung on shared poles.

The highest point of the bridge is located at the intersection of the Coal Harbour Bridge – the rise from Hakaniemenranta is slight and descends equally softly towards Sompasaari. For special situations, the bridge also has a part that can be opened with a mobile crane.
