ŚWINOUJŚCIE, Poland; VIENNA, Austria – The contract for the construction of the Świnoujście tunnel was recently signed. The project will be implemented by a consortium consisting of PORR, Gulermak and Energopol-Szczecin. The contract value is around EUR 150 million and the project is expected to take 48 months to complete.
The total length of the project is approximately 3.2 kilometers. This includes a 1.44-kilometer tunnel boring machine excavation in the slurry shield procedure. The breakout diameter of the tunnel will be 13.5 meters. A two-way roadway will be constructed with traffic lanes with a width of 3.5 meters and evacuation niches will be built using ground freezing. The project will be implemented by the consortium as a Design-Build contract.
Once the tunnel is completed in fall 2022, it will provide a direct connection between Uznam and the Polish mainland. In addition, the journey time will be reduced to just a few minutes, as well as significantly improving the connection to Polish holiday areas in West Pomerania.
The Polish city of Świnoujście extends over the eastern part of the island of Uznam, as well as over the islands of Wolin and Karsibór. Uznam is home to an administration center and service center, as well as a seaside resort with tourist and health resort facilities. About 80 percent of the inhabitants of Świnoujście live on Uznam.
Uznam and Wolin are separated by the Świna river, an arm of the Baltic Sea. Traffic between the islands is carried out via ferry connections across the Świna. Due to the high-capacity utilization of the ferry crossings, waiting times during the holiday season can be up to several hours. Fluctuating weather conditions make ferry operations even more difficult.
