Project plan Matinkylä–Kivenlahti

The project plan for the Matinkylä–Kivenlahti section was completed in May 2012. The implementation requirements of the project and the level of construction costs have been confirmed with this project plan.

A preliminary general plan, Matinkylä–Kivenlahti

Construction costs for various options are presented in the plan (2011). The planning has resulted in a preliminary general plan of the Matinkylä–Kivenlahti section that serves as a good starting point for the following planning phases and the preparation of an underground plan.

Project plan Ruoholahti–Matinkylä

The project plan for the first section was completed in December 2007. Calculations and surveys made based on the plan formed the basis for the project decision. The project plan also serves as the starting point for the construction design of the west metro.

Metro passenger traffic forecast

The demand forecast of the traffic network in the Helsinki metropolitan area has been used as the scaling basis for the west metro. The forecast was prepared by Strafica in 2007. The demand forecast was updated in the spring of 2012, and the latest update was made in August 2012 to correspond to the development of land use.

Environmental Impact Assessment report

Further information on how the metro will affect transport can be found in the Environmental Impact Assessment report.

Feeder network plan

When the operation of the west metro starts from Ruoholahti to Matinkylä, direct bus lines between southern Espoo and Helsinki city centre along Länsiväylä motorway will be replaced with feeder traffic. Buses will transport passengers to metro stations in Espoo, and they can continue their journey by metro to Helsinki. Night-time traffic will continue to be operated with direct bus connections. The traffic and route plans will be specified in more detail as the project proceeds. HSL is responsible for the feeder network planning. The latest information is available on HSL’s blog website (in Finnish).
