Tunnel construction for Gdansk, Poland

Work is now underway on the second section of a new tunnel project in the Polish city of Gdansk. The tunnel runs underneath the Martwa Wisla River. The project is of note as it is the first time a TBM has been used to drive a tunnel in Poland. The tunnel will feature twin tubes, each measuring 1.07km long. The tunnel forms part of the Trasa Slowackiego project and is worth some €210 million.
