The design of the tunnel was implemented by the German-Polish joint venture formed by the design companies SSF Ingenieure AG and Europrojekt Gdansk S.A. in the framework of the overall project “Connection of the airport to Gdansk Harbour – Slowackiego route”. The route is an important link in the new transport network of Gdansk.
The tunnel, built by hydro-shield TBM, has a total length of 1377.5 m and two separated tubes, one in each direction. Where the tunnel crosses the Dead Vistula, the river is around 120 m wide and 12 m deep.
