Current traffic to Stockholm, Sweden from the South Harbour will be transferred to Katajanokka in the centralisation of the development programme, and the Port will withdraw most of its operations from the South Harbour. This will give the City the opportunity to renew the South Harbour area into public urban space. The plans will be implemented in cooperation with the City of Helsinki. The implementation have been planned in a way that allows the construction of the Architecture and Design Museum in the South Harbour.

Makasiini Terminal in the South Harbour were demolished in 2023. Towards the end of the development programme the Port will also hand over the Olympia Terminal and Harbour House to the City of Helsinki for other than port use. Until then, the South Harbour will serve the Stockholm traffic as normal.

However, the needs of international cruise traffic and potential high-speed vessel traffic will be taken into account in the future land use.

After the development programme is completed, the South Harbour will be used as a port for small and medium-sized cruise ships.
