The city of Helsinki has plans for a radical expansion of the tram network within the 2021–2035 time horizon, as laid out in the Helsinki City Plan, approved by the City Council in October 2016. Below is a list of confirmed and proposed future expansions of the network. The largest confirmed projects are the 25-kilometre (16 mi) trunk line 550 ("Jokeri") and the 10-kilometre (6.2 mi) connection in the direction of East Helsinki to the island of Laajasalo, which will include the longest bridge in Finland. Together, these two will effectively double the track length of the network.
