The Kalasatama metro service disruption in 2027

The Junatie metro bridge between Kalasatama and Sörnäinen will be replaced between 2026 and 2028. Metro service will be interrupted between Herttoniemi and Hakaniemi stations from 3 May to 8 December 2027. Kalasatama metro station will be closed from 26 April to 15 December 2027.

The Junatie metro bridge between Kalasatama and Sörnäinen will be replaced between 2026 and 2028.

The replacement of the Junatie metro bridge will require the suspension of metro service for approximately seven months in 2027. This suspension will last from 3 May to 8 December 2027.

During this period, the metro will run from the west to Hakaniemi and from the east to Herttoniemi.

Kalasatama metro station will be closed from 26 April to 15 December 2027 due to construction work on the metro bridge. The station will be closed during the metro service interruption, as well as one week before and one week after this period. During these two weeks, metro trains will pass the station without stopping.

HSL Helsinki Region Transport is planning a replacement service for the duration of the metro service interruption.

Suspending the metro service is necessary

The Junatie metro bridge is in need of replacement. The bridge was originally designed according to the design guidelines of the 1970s and no longer meets current load-bearing requirements.

Recent inspections have revealed deficiencies in the load-bearing capacity of the bridge. In winter 2025, the bridge was outfitted with temporary supports as a risk management measure to allow the metro service to continue safely.

The bridge is currently safe to use, but a decision has been made to bring its replacement forward. The aim is to ensure that the bridge does not have to be closed unexpectedly. The replacement will be carried out in a systematic way, and carefully planned replacement services will be provided during the metro service suspension.
