Tram routes 1 and 1T to be diverted and changes to tram timetables from 29 December

Tram routes 1 and 1T will be diverted via Kamppi from Monday, 12 December. In addition, the timetables of nearly all tram routes will change. For up-to-date routes and timetables, see the Journey Planner.

Trams 1 and 1T will run via Simonkatu and Kamppi starting 29 December. Lasipalatsi and the Natural History Museum will not be served.

The diversion is due to the renovation of the Arkadiankatu bridge and will remain in place until late 2026. The renovation will not affect HSL's bus services. 

Read more about the renovation of the Arkadiankatu bridge on the City of Helsinki's website.

Additionally, nearly all tram timetables will change, with the exception for tram route 5.
