As part of the investment, a viaduct was built over the railway tracks in the line of Trakt św. Wojciecha along with the reconstruction of the road system. The structure was based on three steel arch girders with suspended platforms. As part of the project, a completely new road system was created along the main artery of the Tri-City, which is ul.
