Planned tram projects in Helsinki
The city of Helsinki and the neighbouring city of Vantaa have plans for a radical expansion of the Helsinki tram network within the 2020s and 2030s that would more than double the length of the network from 2021. If completed, the plans would both extend the current tram lines and build new light rail lines.
Projects under construction
Laajasalo
The city council of Helsinki decided on 31 August 2016 to build a tramway to the island of Laajasalo, located to the east of Helsinki city centre. The route will include three new bridges, the longest of which will be the longest in Finland at, and its pylons one of the tallest structures in Helsinki. The bridges will have bicycle and pedestrian lanes in addition to the tramway, but no lanes for private cars. The total length of new double track, including tramways on Laajasalo itself, is about.Vantaa light rail
The Vantaa city council approved the construction of a new light rail line from Mellunmäki to Helsinki Airport in May 2023. The line is projected to open in 2029 with an estimated daily ridership of. Construction began in June 2025.Approved projects
West Helsinki light rail
The Helsinki city council approved the general plan for the West Helsinki trams in January 2021, with an estimated total cost of €160 million. The project, previously known as the Vihdintie light rail, includes a light rail line via Vihdintie towards Kannelmäki, and new city center tram tracks via Topeliuksenkatu to relieve traffic from the crowded track on Mannerheimintie. The new light rail line from the city center to Kannelmäki is estimated to have a daily ridership of by 2030., construction was due to start in 2026.Line reorganisation
The Helsinki Regional Transport Authority is planning to re-organise the current lines as new light rail lines are being built.In April 2022, the plan initially included small- to medium-length extensions, such as the works in Itä-Pasila and Jätkäsaari, and the extension to Laajasalo. Under this plan, the tram lines at the end of 2027 would be arranged as follows:
From roughly 2035, the lines would be arranged as follows:
- Lines 2 and 3 do not turn around at their shared terminus at the Olympia Terminal: they only change their line numbers.
- Lines 3 and 7 will not turn around at their shared terminus at Kaivopuisto: they will only change their line numbers.
- This line and the tramways that comprise it are only tentatively proposed.
- This extension and the tramways that comprise it are only tentatively proposed.
