‘Giant’ trees make way for a new railway line in Gothenburg. Three massive trees were transplanted to make way for the construction of a new tunnel under the Swedish city of Gothenburg. The largest specimen weighed 186 tons and ‘floated’ through the night sky on a 70 m² platform. A railway construction project is under way for local and regional trains in the tunnel for the ‘Västlänken’, the western link. To the video.
