Tunneling under Rostock’s main railway station
Extension of tram network
This project to tunnel under the main railway station of the German city of Rostock, at a depth of 11 m, was completed after a construction period of 2.5 years. In the first stage, bored pile walls were constructed in the platform area, and tunnel roof slabs were added, during three strictly defined track closures, and the platforms were then reconstructed. Then followed the structural work for the first sublevel, to serve the movement of pedestrians below the railway tracks, and for the tunnel and its entry-and-exit structures. In the next stage, the second sublevel was constructed to take the tram line and its stops beneath the railway station. The overall length of the construction project came to 1,100 m, including 300 m of tunnel. In connection with this project, extensive road construction and landscaping works were also required.
