Crown Bridges alliance goes to work

The Crown Bridges project – Kruunusillat – is underway. The project will link the Laajasalo district of eastern Helsinki, the Korkeasaari island and the new Kalasatama district to the Helsinki city centre with a 10-kilometre-long light rail line.

The Crown Bridges light rail line will be implemented as a combination of two project types: the two bridges between Kalasatama and Kruunuvuorenranta and the Korkeasaari earthmoving and construction work will constitute an all-in contract. Other construction work will comply with the alliance model.

A 1.5-year alliance development phase was launched at the end of November 2019. During this phase, the City of Helsinki and the enterprises of the bridge design competition’s winning team will draw up the final content of the project in the scope of the alliance as well as a plan for implementation. Furthermore, the partners will determine the target cost and the incentive system.

The Crown Bridges alliance will also carry out other earthmoving and construction work, street construction and infrastructure development on the light rail connection. One of these projects is the construction of a new Hakaniemi bridge and the demolition of the old bridge. 

The members of the Crown Bridges alliance are the City of Helsinki, YIT Suomi Oy, NRC Group Finland Oy, Ramboll Finland Oy, Sweco Infra & Rail Oy and Sitowise Oy.

Construction is estimated to commence in 2021. The current goal for completion is in 2026. The project timetable will be defined in more detail in 2021.
