🛣️ Świna Tunnel

The Świna Tunnel is a tunnel beneath the Świna Channel in Świnoujście, Poland, connecting the islands of Usedom and Wolin which separate the Szczecin Lagoon from the Baltic Sea in north western Poland. It constitutes the only fixed link between two parts of the city and subsequently between the rest of the country and the center of Świnoujście which prior to the tunnels opening in 2023 was accessible only by ferry.
