Espoo City Council addressed and approved an adjusted project plan for the Matinkylä–Kivenlahti section on 19 March 2018. The adjusted cost estimate for phase two is EUR 1,159 million. Several changes were made to the project during the update process. For example, station areas were increased by almost 10 per cent on average to improve safety, functionality, constructability and maintenance.
The Espoonlahti bus terminal was redesigned as a heated facility integrated with a shopping centre, and the turnaround track at Kivenlahti was extended to improve operational reliability based on the operator’s requirements. In addition, a number of smaller changes and additions were made to the project scope. As a result, the project plan approved in 2018 was significantly broader than the original project plan completed in 2012.
The Matinkylä-Kivenlahti section was handed over to the operator in 2022, and passenger services began on 3 December 2022, earlier than planned. Work included in the Phase II project plan is still continuing in certain locations. These include the construction of a second entrance at Kivenlahti station and a park-and-ride facility at Kaitaa. Länsimetro Oy regularly reports on the project’s progress, costs and forecast updates to the City of Espoo.
