Underground Master Plan

A new underground master plan has been created for Helsinki. It will be used to control the planning of facilities and tunnels in the bedrock underneath the city.

The previous underground master plan, which came into force in 2011, was in need of an update, because some of the space reservations had become obsolete while new space requirements had emerged.

Helsinki’s city plan (2016) will steer the city towards becoming more densely built, and the city’s expansion will make it necessary to transfer some of the operations underground and utilise the underground facilities more efficiently. The new underground master plan will promote a more diverse use of the underground facilities, more systematic utilisation of facilities constructed in the bedrock and better coordination between different types of operations.

Only the most important underground projects will be included in the underground master plan. However, underground projects can also be conducted based on the detailed plan.

The final decision regarding the new underground master plan was be made by the City Council in June 2021.
