The investment project carried out for the purposes of the Forum Gdańsk multifunctional complex included the construction of a new street: Nowe Podwale Grodzkie, reconstruction of existing streets and construction of engineering structures such as a tunnel for pedestrians from the new high-speed urban tram Śródmieście stop or the reconstruction of the Hucisko viaduct.

An integrated interchange has also been constructed, which provides convenient connections between the tram, bus and the high-speed urban tram in an innovative way in Gdańsk. The construction was carried out while maintaining traffic in one of the most crowded areas of Gdańsk.
