Tunnel under Martwa Wisła, Road tunnel in Gdańsk, Poland
The Tunnel under Martwa Wisła is a road passage beneath the river consisting of two parallel tubes, each carrying traffic in both directions with two lanes per direction. The structure extends approximately 1,400 meters (4,600 feet) under the river bed and serves as a major traffic corridor.
Work on the tunnel started in 2011 and finished in 2016, marking a major infrastructure accomplishment for the city. This project was essential for improving cross-river traffic and strengthening connections within the urban area.
The tunnel honors Archbishop Tadeusz Gocłowski, a prominent religious leader in the city, through its official name chosen in 2016. This reflects how the city connects its heritage and important figures to modern infrastructure.
The tunnel handles thousands of vehicles daily and includes multiple safety features for emergency situations. Seven connecting passages between the tubes and emergency facilities in technical buildings ensure safe evacuation if needed.
The tunnel operates under 24-hour supervision by a dedicated team using advanced monitoring systems. This team performs hundreds of maintenance tasks throughout the year to keep the passage safe and running smoothly.
