Porr wins Polish road tunnel contract

A Porr consortium has won the contract for the construction of the Świnoujście tunnel in Poland.

The 3.2km project, includes a 1.44km tunnel boring machine excavation providing a direct link between Uznam and the Polish mainland under the Świna river. The breakout diameter of the tunnel will be 13.5m and a two-way roadway will be constructed with traffic lanes with a width of 3.5m with evacuation niches built using ground freezing.

The consortium consisting of Porr, Gulermak and Energopol-Szczecin is expected to take two years to build the €150M (£133M) tunnel under a design and build contract.

Porr CEO Karl-Heinz Strauss said: “The Świnoujście tunnel is one of our key infrastructure projects in Poland. In cooperation with our Porr colleagues from Poland and Austria as well as the experienced experts from Gulermak and Energopol-Szczecin, we will demonstrate our construction expertise and innovative strength.”

Porr president of the board Piotr Kledzik added: “The design and build project in Świnoujście requires a high degree of flexibility and expertise in technical solutions.”

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 centre and service centre as well as a seaside resort with tourist and health resort facilities. About 80% of the inhabitants of Świnoujście live on Uznam.

The new tunnel will reduce journey times to just a few minutes as well as significantly improving the connection to Polish holiday areas in West Pomerania.

Uznam and Wolin are separated by the Świna river, an arm of the Baltic Sea. Traffic between the islands is currently carried out via ferry connections across the Świna. Due to the high capacity utilisation 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.
