A 24-meter tall ventilation tower has emerged at Järntorget in Gothenburg, puzzling many passersby who have watched it grow over the past year. According to reports from Göteborgs-Posten and Aftonbladet, the silver-colored, twisted conical structure is actually a ventilation tower designed to remove toxic exhaust fumes from the Göta tunnel.
Simon Hulander, project leader at Trafikverket (the Swedish Transport Administration), told Göteborgs-Posten that "the tower will become a fine addition to the city." The tower, which features aluminum plates being mounted on its exterior, is necessary to enable the construction of the new Järnvägsparken (Railway Park) above the tunnel.
the tower will become a fine addition to the city.
The ventilation system will use fans to draw exhaust fumes from the tunnel through a large underground culvert and up through the tower, releasing them higher in the atmosphere. This is required because the fumes currently exit at the tunnel mouth, which would interfere with the planned park above.
Construction is progressing rapidly, with completion scheduled for the end of May 2026, though Hulander indicated work may finish ahead of schedule. The Järnvägsparken, expected to be completed by 2030, will be approximately half the size of a football field and will include a playground with historical themes related to Masthamnen and the railway.
