The Turku Tramway Alliance, comprising the City of Turku, Turku Tramway Ltd., GRK, NRC Group, Ramboll and Sweco, signed an agreement on 28 September 2026 on the implementation of the Turku tramway project. The cost estimate for the first implementation phase is EUR 33.3 million, of which GRK's share is approximately EUR 12 million. The project related to the first implementation phase will be transferred to GRK's order book in the third quarter of 2026.
In May, GRK announced that it would participate in the construction of the new tramway in Turku following the decision made by the Turku City Council on 18 May 2026. The cost estimate for the first implementation phase includes construction work to be carried out in 2027-2028 and tramway design costs. In addition, extensive archaeological excavations will be carried out during these years, with an estimated cost of EUR 15.1 million. The first implementation phase of the project is part of GRK's previously estimated share of approximately EUR 190 million in the entire Turku tramway project. All the amounts stated above are included in the total estimated cost of the Turku tramway project, which is EUR 465.2 million
Construction will begin in early 2027
The first implementation phase will begin in early 2027 and will be completed by the end of 2028. The first implementation phase will comprise the construction of a public transport corridor and the refurbishment of Turku Cathedral Bridge and the surrounding streets. Extensive archaeological excavations will also be carried out in the area.
"We have been planning the implementation of the project for more than two years, and we will finally be able to start construction soon. This will be reflected in the streetscape on Uudenmaankatu and Aninkaistenkatu and at the Turku Cathedral Bridge. We will complete the work in these areas before Turku's 800th anniversary in 2029," says Jouko Viitala, Unit Director at GRK.
In addition to construction, GRK will also provide consultancy services on technical rail systems as part of the project.
The start of the second implementation phase, which will involve the construction of the tramway itself, is contingent on the confirmation of central government funding in the next round of negotiations on land use, housing and transport. The tramway will be completed in 2032, and commercial traffic will start in autumn 2033 after track testing and trial runs.
