Metro, Länsiväylä and cycle paths ensure excellent transport connections for Koivusaari. The new metro station serves nearby residents.
The centre of Helsinki is only 7 minutes away from Koivusaari by metro, and Otaniemi and Tapiola are even closer. The metro will make Koivusaari a district where a car is not needed for living or working.
The Koivusaari metro station opened as West Metro traffic began in 2017. The first users of the station are the residents of western Lauttasaari and Katajaharju. Initially, there will be 4,000–6,000 daily users. The entrance on the Katajaharju side was taken into use first. The entrance on the Koivusaari side will be completed later, and it will open once construction in the area progresses.
Movement will be made as easy and comfortable as possible for pedestrians and cyclists. The goal is to make the main light traffic route, running in parallel with Länsiväylä between Espoo and the centre of Helsinki, work smoothly in the new Koivusaari area.
Koivusaari is extremely accessible from anywhere in the Helsinki region. It has a prime spot by the sea, alongside Länsiväylä and the metro.
A new interchange from Länsiväylä is being planned for Koivusaari. It will replace the Katajaharju interchange. A deck will be built over Länsiväylä with a new street, Koivusaaren puistokatu, that connects the southern and northern parts of Koivusaari. Another new street, Vaskilahdenkatu, will be built between Lauttasaari and Koivusaari.
Parking spaces will be located per block, below the yard decks and in the parking garages. Customer and guest parking is mainly available on the street sides.
