The Crown Bridges (Kruunusillat) project is a new, complex and approximately 10 km long tramway with three bridges linking the cape of Laajasalo, the island of Korkeasaari and the Kalasatama neigbourhood to Helsinki city centre.

At the same time, it offers a new maritime route for pedestrians and cyclists from Laajasalo to the city centre. The connection includes three spectacular bridges of Kruunuvuori, Finken and Merihaka. The 1,200-meter-long Kruunuvuori Bridge will be the longest bridge in Finland when completed.

The Helsinki City Council approved the construction of the project in August 2016. Over the years, various alternatives have been widely examined to implement the public transport connection between the city centre and Laajasalo on the other side of the bay. A tramway over bridges was considered the best alternative. The construction is expected to begin in 2021 and to be completed in 2026.

Among the project participants are various branches of the city’s administration, consultants, and stakeholder groups.

We are responsible for coordinating the Kruunusillat project, including monitoring and coordinating the planning tasks in zoning and various technical fields, and maintaining project schedules. Our work encompasses coordinating street planning, environmental and license issues, information management, communications, interaction, and risk management. 

We also designed the design guidelines. During the drafting phase, several technology field related workshops and design meetings were held between different stakeholders. The manual was officially completed in March 2016. Since then, it has been regularly updated as a web version where it is available to all.
